Description

Description

The NAND01G-B2C is a 1-Gbit device belonging to the NAND SLC large page family. The

device operates with a 1.8 V or 3 V voltage supply. The size of a page is either 2112 bytes

(2048 + 64 spare) or 1056 words (1024 + 32 spare) depending on whether the device has a

x8 or x16 bus width.

The address lines are multiplexed with the data input/output signals on a multiplexed x8 or

x16 input/output bus. This interface reduces the pin count and makes it possible to migrate

to other densities without changing the footprint.

Each block can be programmed and erased up to 100,000 cycles (with ECC on). To extend

the lifetime of NAND flash devices, the implementation of an error correction code (ECC) is

mandatory.

The devices feature a write protect pin that allows performing hardware protection against

program and erase operations.

The devices feature an open-drain ready/busy output that can be used to identify if the

program/erase/read (P/E/R) controller is currently active. 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 Copy Back Program command is available to optimize the management of defective

blocks. When a page program operation fails, the data can be programmed in another page

without having to resend the data to be programmed.

The cache read feature is also implemented according to ONFI 1.0 specification.

All devices have the chip enable don’t care feature, which allows the bus to be shared

among several memories active at the same time, as chip enable transitions during the

latency time do not stop the read operation. Program and erase operations can never be

interrupted by chip enable transitions.

The devices are available in the following packages:

●

TSOP48 (12 x 20 mm)

●

VFBGA63 (9 x 11 x 1.05 mm, 0.8 mm pitch)

●

VFBGA153 (8 x 9 x 0.9 mm, 0.5 mm pitch)

and come with three security features:

●

OTP (one time programmable) area, which is a restricted access area where sensitive

data/code can be stored permanently.

●

Serial number (unique identifier), which allows the devices to be uniquely identified.

●

Non-volatile protection to lock sensible data permanently. For more details of this

option contact your nearest Numonyx sales office.

These security features are subject to an NDA (non-disclosure agreement) and are,

therefore, not described in the datasheet. For more details about them, refer to the nearest

Numonyx sales office.

For information on how to order these options refer to Table 28: Ordering information

scheme. Devices are shipped from the factory with block 0 always valid and the memory

content bits, in valid blocks, erased to ’1’.

See Table 2: Product description, for all the devices available in the family.
