

Erase suspend/erase resume

a sector that is not being erased, then resumes the erase

operation



Data# polling and toggle bits

erase operations



Unlock bypass program command

– Reduces overall programming time when issuing multiple program

command sequences

Hardware Features



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 the

read mode



WP#/ACC input pin

– Write protect (WP#) function protects sectors 0, 1, 140, and 141,

regardless of sector protect status

– Acceleration (ACC) function accelerates program timing



Sector Protection

– Hardware method to prevent any program or erase operation

within a sector

– Temporary Sector Unprotect allows changing data in protected

sectors in-system

Package Options



48-ball Fine-pitch BGA



48-pin TSOP

Performance Characteristics



High performance

– Access time as fast as 55 ns

– Program time: 7 µs/word typical using accelerated programming

function

General Description

The S29JL064J is a 64 Mbit, 3.0 volt-only flash memory device, organized as 4,194,304 words of 16 bits each or 8,388,608 bytes of

8 bits each. Word mode data appears on DQ15–DQ0; byte mode data appears on DQ7–DQ0. The device is designed to be

programmed in-system with the standard 3.0 volt V

supply, and can also be programmed in standard EPROM programmers. The

device is available with an access time of 55, 60, 70 ns and is offered in a 48-ball FBGA or 48-pin TSOP package. Standard control

pins—chip enable (CE#), write enable (WE#), and output enable (OE#)—control normal read and write operations, and avoid bus

contention issues. The device requires only a

single 3.0 volt power supply

for both read and write functions. Internally generated

and regulated voltages are provided for the program and erase operations.

S29JL064J

Simultaneous Read/Write Operations with Zero Latency

The Simultaneous Read/Write architecture provides

simultaneous operation

by dividing the memory space into

four banks,

two

8 Mb banks with small and large sectors, and two 24 Mb banks of large sectors. Sector addresses are fixed, system software can be

used to form user-defined bank groups.

During an Erase/Program operation, any of the three non-busy banks may be read from. Note that only two banks can operate

simultaneously. The device can improve overall system performance by allowing a host system to program or erase in one bank,

then immediately and simultaneously read from the other bank, with zero latency. This releases the system from waiting for the

completion of program or erase operations.

The S29JL064J is organized as a dual boot device with both top and bottom boot sectors.

S29JL064J Features

The

Secured Silicon Region

is an extra 256 byte sector capable of being permanently locked by Cypress or customers. The

Secured Silicon Customer Indicator Bit (DQ6) is permanently set to 1 if the part has been customer locked, and permanently set to 0

if the part has been factory locked. This way, customer lockable parts can never be used to replace a factory locked part.

Factory locked parts provide several options. The Secured Silicon Region may store a secure, random 16 byte ESN (Electronic

Serial Number), customer code (programmed through Cypress programming services), or both. Customer Lockable parts may

utilize the Secured Silicon Region as bonus space, reading and writing like any other flash sector, or may permanently lock their own

code there.

The device offers complete compatibility with the

JEDEC 42.4 single-power-supply Flash command set standard.

Commands

are written to the command register using standard microprocessor write timings. Reading data out of the device is similar to reading

from other Flash or EPROM devices.

The host system can detect whether a program or erase operation is complete by using the device

status bits:

RY/BY# pin, DQ7

(Data# Polling) and DQ6/DQ2 (toggle bits). After a program or erase cycle has been completed, the device automatically returns to

the read mode.

The

sector erase architecture

allows memory sectors to be erased and reprogrammed without affecting the data contents of other

sectors. The device is fully erased when shipped from the factory.

Hardware data protection

measures include a low V

detector that automatically inhibits write operations during power

transitions. The

hardware sector protection

feature disables both program and erase operations in any combination of the sectors

of memory. This can be achieved in-system or via programming equipment.

The Erase Suspend/Erase Resume

feature enables the user to put erase on hold for any period of time to read data from, or

program data to, any sector that is not selected for erasure. True background erase can thus be achieved. If a read is needed from

the Secured Silicon Region (One Time Promgram area) after an erase suspend, then the user must use the proper command

sequence to enter and exit this region.

The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters

the

automatic sleep mode.

The system can also place the device into the

standby mode.

Power consumption is greatly reduced in

both modes.
