Part Number: M28W320

Function: 32 MBIT (2MB X16, BOOT BLOCK) LOW VOLTAGE FLASH MEMORY

Package: TFBGA47, TSOP48 Type

Manufacturer: STMicroelectronics

Pinouts:

 

Description

The M28W320 is a 32 Mbit (2 Mbit x 16) nonvolatile Flash memory that can be erased electricallyat the block level and programmed in-system on aWord-by-Word basis. These operations can beperformed using a single low voltage (2.7 to 3.6V)supply. VDDQallows to drive the I/O pin down to1.65V. An optional 12V VPPpower supply is pro-vided to speed up customer programming.

Features

1. Supply Voltage

(1) Vdd = 2.7V to 3.6V Core Power Supply
(2) Vddq = 1.65V to 3.6V for Input/Output
(3) Vpp= 12V for fast Program (optional)

2. Access Time: 70, 80, 90, 100ns

3. Programming Time

(1) 10µs typical
(2) Double Word Programming Option
(3) Quadruple Word Programming Option

4. Common Flash Interface

5. Memory Blocks

(1) Parameter Blocks (Top or Bottom location)
(2) Main Blocks

6. Block Locking

(1) All blocks locked at Power Up
(2) Any combination of blocks can be locked
(3) WP for Block Lock-Down
