All devices have the Chip Enable Don’t Care feature, which allows code to be directly

downloaded by a microcontroller, as Chip Enable transitions during the latency time do not

stop the read operation.

All devices have the option of a Unique Identifier (serial number), which allows each device

to be uniquely identified.

The Unique Identifier options is subject to an NDA (Non Disclosure Agreement) and so not

described in the datasheet. For more details of this option contact your nearest ST Sales

office.

The devices are available in the following packages:

●TSOP48 (12 x 20mm)

●VFBGA63 (9.5 x 12 x 1mm, 0.8mm pitch) for NAND02G-B2C devices.

●VFBGA63 (9 x 11 x 1mm, 0.8mm pitch) for NAND01G-B2B devices.

In order to meet environmental requirements, ST offers the NAND01G-B2B and NAND02G-

B2C in ECOPACK? packages. ECOPACK packages are Lead-free. The category of second

Level Interconnect is marked on the package and on the inner box label, in compliance with

JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also

marked on the inner box label. ECOPACK is an ST trademark.

NAND01G-B2B, NAND02G-B2C Memory array organization 13/622 Memory array organization

The memory array is made up of NAND structures where 32 cells are connected in series.

The memory array is organized in blocks where each block contains 64 pages. The array is

split into two areas, the main area and the spare area. The main area of the array is used to

store data whereas the spare area is typically used to store Error correction Codes, software

flags or Bad Block identification.

In x8 devices the pages are split into a 2048 Byte main area and a spare area of 64 Bytes.

In the x16 devices the pages are split into a 1,024 Word main area and a 32 Word spare

area. Refer to Figure 5: Memory Array Organization .

2.1 Bad blocks

The NAND Flash 2112 Byte/ 1056 Word Page devices may contain Bad Blocks, that is

blocks that contain one or more invalid bits whose reliability is not guaranteed. Additional

Bad Blocks may develop during the lifetime of the device.

The Bad Block Information is written prior to shipping (refer to Section 8.1: Bad Block

Management for more details).

Table 4: Valid Blocks shows the minimum number of valid blocks in each device. The values

shown include both the Bad Blocks that are present when the device is shipped and the Bad

Blocks that could develop later on.

These blocks need to be managed using Bad Blocks Management, Block Replacement or

Error Correction Codes (refer to Section 8: Software algorithms ).

NAND01G-B2B, NAND02G-B2C Signals description 15/623 Signals description

See Figure 2: Logic Diagram , and T able 3: Signal Names , for a brief overview of the signals

connected to this device.

3.1 Inputs/Outputs (I/O0-I/O7)

Input/Outputs 0 to 7 are used to input the selected address, output the data during a Read

operation or input a command or data during a Write operation. The inputs are latched on

the rising edge of Write Enable. I/O0-I/O7 are left floating when the device is deselected or

the outputs are disabled.

3.2 Inputs/Outputs (I/O8-I/O15)

Input/Outputs 8 to 15 are only available in x16 devices. They are used to output the data

during a Read operation or input data during a Write operation. Command and Address

Inputs only require I/O0 to I/O7.

The inputs are latched on the rising edge of Write Enable. I/O8-I/O15 are left floating when

the device is deselected or the outputs are disabled.

3.3 Address Latch Enable (AL)

The Address Latch Enable activates the latching of the Address inputs in the Command

Interface. When AL is high, the inputs are latched on the rising edge of Write Enable.

3.4 Command Latch Enable (CL)

The Command Latch Enable activates the latching of the Command inputs in the Command

Interface. When CL is high, the inputs are latched on the rising edge of Write Enable.

3.5 The Chip Enable input activates the memory control logic, input buffers, decoders and

sense amplifiers. When Chip Enable is low, V IL , the device is selected. If Chip Enable goes

high, v IH , while the device is busy, the device remains selected and does not go into standby

mode.

3.6 The Read Enable pin, R, controls the sequential data output during Read operations. Data

is valid t RLQV after the falling edge of R. The falling edge of R also increments the internal

column address counter by one.

Signals description NAND01G-B2B, NAND02G-B2C 16/62 3.7 Data latches. Both addresses and data are latched on the rising edge of Write Enable.

During power-up and power-down a recovery time of 10μs (min) is required before the

Command Interface is ready to accept a command. It is recommended to keep Write Enable high during the recovery time.

3.8 Write Protect (WP)

The Write Protect pin is an input that gives a hardware protection against unwanted program

or erase operations. When Write Protect is Low, V IL , the device does not accept any

program or erase operations.

It is recommended to keep the Write Protect pin Low, V IL , during power-up and power-down.

3.9 Ready/Busy (RB)

Controller is currently active. When Ready/Busy is Low, V OL , a read, program or erase

operation is in progress. When the operation completes Ready/Busy goes High, V OH .

The use of an open-drain output allows the Ready/Busy pins from several memories to be

connected to a single pull-up resistor. A Low will then indicate that one, or more, of the

memories is busy.

Refer to the Section 11.1: Ready/Busy Signal electrical characteristics for details on how to

calculate the value of the pull-up resistor.

3.10 V DD Supply Voltage

V DD provides the power supply to the internal core of the memory device. It is the main

power supply for all operations (read, program and erase).

An internal voltage detector disables all functions whenever V DD is below V LKO (see

Table 22 and Table 23) to protect the device from any involuntary program/erase during

power-transitions.

Each device in a system should have V DD decoupled with a 0.1μF capacitor. The PCB track

widths should be sufficient to carry the required program and erase currents.

3.11 V SS Ground

Ground, V SS, is the reference for the power supply. It must be connected to the system

ground.
