GENERAL DESCRIPTION

The MX29LV320M H/L is a 32-mega bit Flash memory organized as 4M bytes of 8 bits or 2M words of 16 bits. MXICs Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV320M H/L is packaged in 56-pin TSOP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES

GENERAL FEATURES

• Single Power Supply Operation

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

• Configuration

- 4,194,304 x 8 / 2,097,152 x 16 switchable

• Sector structure

- 64KB(32KW) x 64

• Sector Protection/Chip Unprotect

- Provides sector group protect function to prevent program or erase operation in the protected sector group

- Provides chip unprotect function to allow code changes

- Provides temporary sector group unprotect function for code changes in previously protected sector groups

• Secured Silicon Sector

- Provides a 128-word OTP area for permanent, secure identification

- Can be programmed and locked at factory or by customer

• Latch-up protected to 250mA from -1V to VCC + 1V

• Low VCC write inhibit is equal to or less than 1.5V

• Compatible with JEDEC standard

- Pin-out and software compatible to single power supply Flash

PERFORMANCE

• High Performance

- Fast access time: 70R/90ns

- Page read time: 25ns

- Sector erase time: 0.5s (typ.)

- 4 word/8 byte page read buffer

- 16 word/ 32 byte write buffer: reduces programming time for multiple-word/byte updates

• Low Power Consumption

- Active read current: 18mA(typ.)

- Active write current: 20mA(typ.)

- Standby current: 20uA(typ.)

• Minimum 100,000 erase/program cycle

• 20-years data retention

SOFTWARE FEATURES

• Support Common Flash Interface (CFI)

- Flash device parameters stored on the device and provide the host system to access.

• Program Suspend/Program Resume

- Suspend program operation to read other sectors

• Erase Suspend/ Erase Resume

- Suspends sector erase operation to read data/program other sectors

• Status Reply

- Data# polling & Toggle bits provide detection of program and erase operation completion

HARDWARE FEATURES

• Ready/Busy (RY/BY#) Output

- Provides a hardware method of detecting program and erase operation completion

• Hardware Reset (RESET#) Input

- Provides a hardware method to reset the internal state machine to read mode

• WP#/ACC input

- Write protect (WP#) function allows protection highest or lowest sector, regardless of sector protection settings

- ACC (high voltage) accelerates programming time for higher throughput during system

PACKAGE

• 56-pin TSOP

• All Pb-free devices are RoHS Compliant
