Flash Memory Features
ARCHITECTURAL ADVANTAGES
s
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
s
Data# Polling and Toggle Bits
— Provides a software method of detecting the status of
program or erase cycles
s
Unlock Bypass Program command
— Reduces overall programming time when issuing multiple
program command sequences
HARDWARE FEATURES
s
Any combination of sectors can be erased
s
Ready/Busy# output (RY/BY#)
— Hardware method for detecting program or erase cycle
completion
s
Secured Silicon (SecSi) Sector: Extra 256 Byte sector
—
Factory locked and identifiable:
16 bytes available for
secure, random factory Electronic Serial Number; verifiable
as factory locked through autoselect function.
—
Customer lockable:
Sector is one-time programmable. Once
locked, data cannot be changed
s
Hardware reset pin (RESET#)
— Hardware method of resetting the internal state machine to
reading array data
s
Zero Power Operation
— Sophisticated power management circuits reduce power
consumed during inactive periods to nearly zero
s
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
s
Top or bottom boot block
s
Manufactured on 0.17 µm process technology
s
Compatible with JEDEC standards
— Pinout and software compatible with single-power-supply
flash standard
s
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
PERFORMANCE CHARACTERISTICS
s
High performance
— Access time as fast as 70 ns
— Program time: 4 µs/word typical utilizing Accelerate function
pSRAM Features
s
