32 Megabit (4 M x 8-Bit/2 M x 16-Bit) CMOS 3.0 Volt-only, Simultaneous Operation Flash
Memory and 4 Mbit (256 K x 16-Bit) Static RAM
DISTINCTIVE CHARACTERISTICS
MCP Features
Power supply voltage of 2.7 to 3.3 volt
■
■
High performance
— Flash Access time as fast as 70 ns
— SRAM access time as fast as 55 ns
Package
— 73-Ball FBGA
■
■
Operating Temperature
— –40°C to +85°C
Flash Memory Features
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
■
■
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
■
Zero Power Operation
— Sophisticated power management circuits reduce power
consumed during inactive periods to nearly zero
■
Top or bottom boot block
■
Manufactured on 0.17 μm process technology
■
Compatible with JEDEC standards
— Pinout and software compatible with single-power-supply
flash standard
PERFORMANCE CHARACTERISTICS
High performance
— Access time as fast as 70 ns
— Program time: 4 μs/word typical utilizing Accelerate function
■
■
Ultra low power consumption (typical values)
— 2 mA active read current at 1 MHz
— 10 mA active read current at 5 MHz
— 200 nA 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
Data Management Software (DMS)
— AMD-supplied software manages data programming and
erasing, enabling EEPROM emulation
— Eases sector erase limitations
■
■
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
SRAM Features
Power dissipation
— Operating: 22 mA maximum for 70 ns, 30 mA maximum for
55 ns
— Standby: 10 μA maximum
