PRELIMINARY

(May, 2005, Version 0.0)

AMIC Technology, Corp.

DISTINCTIVE CHARACTERISTICS

ARCHITECTURAL ADVANTAGES

Simultaneous Read/Write operations

- Data can be continuously read from one bank while

executing erase/program functions in other bank

- Zero latency between read and write operations

Multiple bank architectures

- Three devices available with different bank sizes (refer to

Table 2)

Package options

- 48-ball TFBGA

- 48-pin TSOP

Top or bottom boot block

Manufactured on 0.18 µm process technology

- Compatible with AMD AM29DL32xD device

Compatible with JEDEC standards

- Pinout and software compatible with single-power-supply

flash standard

PERFORMANCE CHARACTERISTICS

High performance

- Access time as fast as 70ns

- Program time: 7µs/word typical utilizing Accelerate

function

Ultra low power consumption (typical values)

- 2mA active read current at 1MHz

- 10mA active read current at 5MHz

- 200nA in standby or automatic sleep mode

Minimum 1 million write cycles guaranteed per sector

20 Year data retention at 125°C

- Reliable operation for the life of the system

SOFTWARE FEATURES

Supports Common Flash Memory Interface (CFI)

Erase Suspend/Erase Resume

- Suspends erase operations to allow programming in

same bank

Data Polling and Toggle Bits

- Provides a software method of detecting the status of

program or erase cycles

Unlock Bypass Program command

- Reduces

overall

programming

time

when

issuing

multiple program command sequences

HARDWARE FEATURES

Any combination of sectors can be erased

Ready/ Busy output (RY/BY )

- Hardware method for detecting program or erase cycle

completion

Hardware reset pin (RESET )

- Hardware method of resetting the internal state machine

to reading array data

WP /ACC input pin

- Write protect ( WP ) function allows protection of two

outermost boot sectors, regardless of sector protect

status

- Acceleration (ACC) function accelerates program timing

Sector protection

- Hardware method of locking a sector, either in-system or

using programming equipment, to prevent any program

or erase operation within that sector

- Temporary Sector Unprotect allows changing data in

protected sectors in-system

Software temporary sector/sector block unprotect command

Software sector protect/unprotect command
