GENERAL DESCRIPTION

The MX25L4005A is a CMOS 4,194,304 bit serial Flash memory, which is configured as 524,288 x 8 internally. The MX25L4005A feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by CS# input.

The MX25L4005A provide sequential read operation on whole chip.

FEATURES

GENERAL

? Serial Peripheral Interface (SPI) compatible -- Mode 0 and Mode 3

? 4,194,304 x 1 bit structure

? 128 Equal Sectors with 4K byte each

- Any Sector can be erased individually

? 8 Equal Blocks with 64K byte each

- Any Block can be erased individually

? Single Power Supply Operation

- 2.7 to 3.6 volt for read, erase, and program operations

? Latch-up protected to 100mA from -1V to Vcc +1V

? Low Vcc write inhibit is from 1.5V to 2.5V

PERFORMANCE

? High Performance

- Fast access time: 85MHz serial clock (15pF + 1TTL Load) and 66MHz serial clock (30pF + 1TTL Load)

- Fast program time: 1.4ms(typ.) and 5ms(max.)/page (256-byte per page)

- Fast erase time: 60ms(typ.) and 120ms(max.)/sector (4K-byte per sector) ; 1s(typ.) and 2s(max.)/block (64K-byte per block)

? Low Power Consumption

- Low active read current: 12mA(max.) at 85MHz, 8mA(max.) at 66MHz and 4mA(max.) at 33MHz

- Low active programming current: 15mA (max.)

- Low active erase current: 15mA (max.)

- Low standby current: 10uA (max.)

- Deep power-down mode 1uA (typical)

? Minimum 100,000 erase/program cycles

? 10 years data retention

SOFTWARE FEATURES

? Input Data Format

- 1-byte Command code

? Block Lock protection

- The BP0~BP2 status bit defines the size of the area to be software protected against Program and Erase instructions

? Auto Erase and Auto Program Algorithm

- Automatically erases and verifies data at selected sector

- Automatically programs and verifies data at selected page by an internal algorithm that automatically times the program pulse widths (Any page to be programed should have page in the erased state first)

? Status Register Feature

? Electronic Identification

- JEDEC 2-byte Device ID

- RES command, 1-byte Device ID

HARDWARE FEATURES
