PRELIMINARY

Am42DL32x4G

Stacked Multi-Chip Package (MCP) Flash Memory and SRAM

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

SOFTWARE FEATURES

MCP Features

■ Power supply voltage of 2.7 to 3.3 volt

■ Data Management Software (DMS)

—

AMD-supplied software manages data programming and

erasing, enabling EEPROM emulation

Eases sector erase limitations

■ High performance

—

Flash Access time as fast as 70 ns

SRAM access time as fast as 55 ns

—

■ Supports Common Flash Memory Interface (CFI)

■ Erase Suspend/Erase Resume

■ Package

—

73-Ball FBGA

—

Suspends erase operations to allow programming in same

bank

■ Operating Temperature

—

–40°C to +85°C

■ Data# Polling and Toggle Bits

—

Provides a software method of detecting the status of

program or erase cycles

Flash Memory Features

■ Unlock Bypass Program command

ARCHITECTURAL ADVANTAGES

—

Reduces overall programming time when issuing multiple

program command sequences

■ 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

HARDWARE FEATURES

—

■ Any combination of sectors can be erased

■ Secured Silicon (SecSi) Sector: Extra 256 Byte sector

■ Ready/Busy# output (RY/BY#)

—

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

—

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

■ Zero Power Operation

Sophisticated power management circuits reduce power

consumed during inactive periods to nearly zero

—

■ WP#/ACC input pin

—

Write protect (WP#) function allows protection of two outermost

boot sectors, regardless of sector protect status

■ Top or bottom boot block

—

Acceleration (ACC) function accelerates program timing

■ Manufactured on 0.17 µm process technology

■ Compatible with JEDEC standards

■ 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

—

Pinout and software compatible with single-power-supply

flash standard

—

Temporary Sector Unprotect allows changing data in

protected sectors in-system

PERFORMANCE CHARACTERISTICS

■ High performance

—

Access time as fast as 70 ns

SRAM Features

■ Power dissipation

Program time: 4 µs/word typical utilizing Accelerate function

■ Ultra low power consumption (typical values)

—

Operating: 22 mA maximum for 70 ns, 30 mA maximum for

—

2 mA active read current at 1 MHz

55 ns

10 mA active read current at 5 MHz

200 nA in standby or automatic sleep mode

—

Standby: 10 µA maximum

■ CE1s# and CE2s Chip Select

■ Minimum 1 million write cycles guaranteed per sector

■ 20 Year data retention at 125°C

■ Power down features using CE1s# and CE2s

■ Data retention supply voltage: 1.5 to 3.3 volt

■ Byte data control: LB#s (DQ7–DQ0), UB#s (DQ15–DQ8)

—

Reliable operation for the life of the system
