General Description

The A29L160 is a 16Mbit, 3.0 volt-only Flash memory organized as 2,097,152 bytes of 8 bits or 1,048,576 words of 16 bits each. The 8 bits of data appear on I/O0 - I/O7; the 16 bits of data appear on I/O0~I/O15. The A29L160 is offered in 48-ball FBGA, 44-pin SOP and 48-Pin TSOP packages. This device is designed to be programmed in-system with the standard system 3.0 volt VCC supply. Additional 12.0 volt VPP is not required for in-system write or erase operations. However, the A29L160 can also be programmed in standard EPROM programmers.

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:

- 70/90/120 (max.)

■ Current:

- 9 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 KbyteX31 sectors

- 8 Kword/ 4 KwordX2/ 16 Kword/ 32 KwordX31 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

■ 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

■ CFI (Common Flash Interface) compliant

- Provides device-specific information to the system, allowing host software to easily reconfigure for different Flash devices

■ 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 (not available on 44-pin SOP)

■ 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

- All Pb-free (Lead-free) products are RoHS compliant
