S29C51001T/S29C51001B

1 MEGABIT (131,072 x 8 BIT)

5 VOLT CMOS FLASH MEMORY

Features

Description

The S29C51001T/S29C51001B is a high speed

131,072 x 8 bit CMOS flash memory. Programming

or erasing the device is done with a single 5 Volt

power supply. The device has separate chip enable

CE, program enable WE, and output enable OE

controls to eliminate bus contention.

The S29C51001T/S29C51001B offers a combi-

nation of features: Boot Block with Sector Erase

Mode. The end of program/erase cycle is detected

■ 128Kx8-bit Organization

■ Address Access Time: 70, 90, 120 ns

■ Single 5V ± 10% Power Supply

■ Sector Erase Mode Operation

■ 8KB Boot Block (lockable)

■ 512 bytes per Sector, 256 Sectors

– Sector-Erase Cycle Time: 10ms (Max)

– Byte-Program Cycle Time: 20µs (Max)

■ Minimum 10,000 Erase-Program Cycles

■ Low power dissipation

– Active Read Current: 20mA (Typ)

– Active Program Current: 30mA (Typ)

– Standby Current: 100µA (Max)

■ Hardware Data Protection

by DATA Polling of I/O or by the Toggle Bit I/O .

The S29C51001T/S29C51001B features a

sector erase operation which allows each sector to

be erased and reprogrammed without affecting

data stored in other sectors. The device also

supports full chip erase.

Boot block architecture enables the device to

boot from a protected sector loaded either at the

top (S29C51001T) or the bottom (S29C51001B)

sector. All inputs and outputs are CMOS and TTL

compatible.

■ Low V Program Inhibit Below 3.2V

■ Self-timed program/erase operations with end-

of-cycle detection

– DATA Polling

– Toggle Bit

■ CMOS and TTL Interface

■ Available in two versions

– S29C51001T (Top Boot Block)

– S29C51001B (Bottom Boot Block)

■ Packages:

The S29C51001T/S29C51001B is ideal for

applications that require updatable code and data

storage.

– 32-pin Plastic DIP

– 32-pin TSOP-I

– 32-pin PLCC
