M58PR256LE
M58PR512LE M58PR001LE
256-Mbit, 512-Mbit or 1-Gbit (× 16, multiple bank, multilevel, burst)
1.8 V supply Flash memories
Features
■ Supply voltage
– VDD = 1.7 V to 2.0 V for program, erase
and read
– VDDQ = 1.7 V to 2.0 V for I/O buffers
– VPP = 9 V for fast program
■ Synchronous/asynchronous read
– Synchronous burst read mode:
108 MHz, 66 MHz
– Asynchronous page read mode
– Random access: 96 ns
■ Programming time
– 4.2 µs typical word program time using
Buffer Enhanced Factory Program
command
■ Memory organization
– Multiple bank memory array:
32 Mbit banks (256 Mb devices)
64 Mbit banks (512 Mb devices)
128 Mbit banks (1 Gb devices)
– Four EFA (extended flash array) blocks of
64 Kbits
■ Dual operations
– Program/erase in one bank while read in
others
– No delay between read and write
operations
Wafer
■ Security
– 64 bit unique device number
– 2112 bit user programmable OTP cells
■ CFI (common Flash interface)
■ 100 000 program/erase cycles per block
■ Electronic signature
– Manufacturer code: 20h
– 256 Mbit device: 8818
– 512 Mbit device: 8819
– 1 Gbit device: 880F
■ Block locking
– All blocks locked at power-up
– Any combination of blocks can be locked
with zero latency
– WP for block lock-down
– Absolute Write protection with VPP = VSS
The M58PRxxxLE memories are only available as part of a multichip package device.
