A29160A Series
2M X 8 Bit / 1M X 16 Bit CMOS 5.0 Volt-only,
Boot Sector Flash Memory
Features
Single power supply operation
- Full voltage range: 4.5 to 5.5 volt for read and write
operations
Access time:
- 55ns (max.)
Current:
- 20mA typical active read current
- 30mA typical program/erase current
- 6uA 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:
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
Industrial operating temperature range: -40ºC to +85ºC 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
Minimum 100,000 program/erase cycles per sector
20-year data retention at 125ºC
- 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
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
WP input pin (48 pins TSOP, TFBGA)
- At VIL, protects the 16Kbyte boot sector from erasure
regardless of sector protect/unprotect status.
- At VIH, allows removal of boot sector protection.
Package options
- 48-pin TSOP (I) or 48-ball TFBGA
- All Pb-free (Lead-free) products are RoHS2.0 compliant
General Description
The A29160A 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/O0 - I/O7; the 16
bits of data appear on I/O0~I/O15. The is offered in 48-ball
FBGA 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 A29160A
can also be programmed in standard EPROM programmers.
The A29160A has the first toggle bit, I/O6, which indicates
whether an Embedded Program or Erase is in progress, or it
is in the Erase Suspend. Besides the I/O6 toggle bit, the
A29160A has a second toggle bit, I/O2, to indicate whether
the addressed sector is being selected for erase. The
A29160A also offers the ability to program in the Erase
Suspend mode. The standard A29160A offers access time of
55ns, allowing high-speed microprocessors to operate
without wait states. To eliminate bus contention the device
has separate chip enable ( CE ), write enable ( WE ) and
output enable ( OE ) controls.
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 A29160A is entirely software command set compatible
with the JEDEC single-power-supply Flash standard.
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.
Device programming occurs by writing the proper program
command sequence. This initiates the Embedded Program
