512K X 8 Bit / 256K X 16 Bit CMOS 3.0 Volt-only, Boot Sector Flash Memory

AMIC Technology 

A29L400A Series

Preliminary

512K X 8 Bit / 256K X 16 Bit CMOS 3.0 Volt-only,

Boot Sector Flash Memory

Features

Single power supply operation

- Full voltage range: 2.7 to 3.6 volt read and write

operations for battery-powered applications

- Regulated voltage range: 3.0 to 3.6 volt read and write

operations for compatibility with high performance 3.3

volt microprocessors

Access times:

- 70/90 (max.)

Current:

- 4 mA typical active read current

- 20 mA typical program/erase current

- 200 nA typical CMOS standby

- 200 nA Automatic Sleep Mode current

Flexible sector architecture

- 16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX7 sectors

- 8 Kword/ 4 KwordX2/ 16 Kword/ 32 KwordX7 sectors

- Any combination of sectors can be erased

- Supports full chip erase

- Sector protection:

A hardware method of protecting sectors to prevent

any inadvertent program or erase operations within that

sector. Temporary Sector Unprotect feature allows

code changes in previously locked sectors

Extended operating temperature range: -40°C ~ +85°C

for –U series

Unlock Bypass Program Command

- Reduces overall programming time when issuing

multiple program command sequence

Top or bottom boot block configurations available

Embedded Algorithms

- Embedded Erase algorithm will automatically erase the

entire chip or any combination of designated sectors

and verify the erased sectors

- Embedded Program algorithm automatically writes and

verifies data at specified addresses

Typical 100,000 program/erase cycles per sector

20-year data retention at 125°C

- Reliable operation for the life of the system

Compatible with JEDEC-standards

- Pinout and software compatible with single-power-

supply Flash memory standard

- Superior inadvertent write protection

Data Polling and toggle bits

- Provides a software method of detecting completion of

program or erase operations

Ready / BUSY pin (RY / BY )

- Provides a hardware method of detecting completion of

program or erase operations

Erase Suspend/Erase Resume

- Suspends a sector erase operation to read data from,

or program data to, a non-erasing sector, then

resumes the erase operation

Hardware reset pin (RESET )

- Hardware method to reset the device to reading array

data

Package options

- 44-pin SOP or 48-pin TSOP (I) or 48-ball TFBGA
