Features
General Description
The A29160 is a 16Mbit, 5.0 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/O
bits of data appear on I/O
FBGA, 44-pin SOP and 48-Pin TSOP packages. This device
is designed to be programmed in-system with the standard
system 5.0 volt VCC supply. Additional 12.0 volt VPP is not
required for in-system write or erase operations. However,
the A29160 can also be programmed in standard EPROM
programmers.
The A29160 has the first toggle bit, I/O
whether an Embedded Program or Erase is in progress, or it
is in the Erase Suspend. Besides the I/O
A29160 has a second toggle bit, I/O
addressed sector is being selected for erase. The A29160
also offers the ability to program in the Erase Suspend mode.
The standard A29160 offers access times of 55 and 70,
allowing high-speed microprocessors to operate without wait
(April, 2010, Version 0.2)
Single power supply operation
- Full voltage range: 4.5 to 5.5 volt for read and write
Access times:
- 55/70 (max.)
Current:
- 20 mA typical active read current
- 30 mA typical program/erase current
- 0.5uA typical CMOS standby ( WP = VCC or Float)
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:
Unlock Bypass Program Command
- Reduces overall programming time when issuing
Top or bottom boot block configurations available
Embedded Algorithms

The device requires only a single 5.0 volt power supply for
both read and write functions. Internally generated and
regulated voltages are provided for the program and erase
operations.
The A29160 is entirely software command set compatible
with the JEDEC single-power-supply
Commands are written to the command register using
standard microprocessor write timings. Register contents
serve as input to an internal state-machine that controls the
erase and programming circuitry. Write cycles also internally
latch addresses and data needed for the programming and
erase operations. Reading data out of the device is similar to
reading from other Flash or EPROM devices.
