32 Megabit (4M x 8-Bit/2M x 16-Bit) CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory

AMIC Technology 

A29DL32x Series

sleep mode is independent of the CE , WE and OE control

signals. Standard address access timings provide new data

when addresses are changed. While in sleep mode, output

data is latched and always available to the system. ICC4 in the

DC Characteristics table represents the automatic sleep

mode current specification.

RESET : Hardware Reset Pin

The RESET pin provides a hardware method of resetting

the device to reading array data. When the system drives the

RESET pin low for at least a period of tRP, the device

immediately terminates any operation in progress, tristates

all data output pins, and ignores all read/write attempts for

the duration of the RESET pulse. The device also resets the

internal state machine to reading array data. The operation

that was interrupted should be reinitiated once the device is

ready to accept another command sequence, to ensure data

integrity.

Current is reduced for the duration of the RESET pulse.

When RESET is held at VSS ± 0.3V, the device draws

CMOS standby current (ICC4 ). If RESET is held at VIL but not

within VSS ± 0.3V, the standby current will be greater.

The RESET pin may be tied to the system reset circuitry. A

system reset would thus also reset the Flash memory,

enabling the system to read the boot-up firmware from the

Flash memory.

If RESET is asserted during a program or erase operation,

the RY/ BY pin remains a “0” (busy) until the internal reset

operation is complete, which requires a time tREADY (during

Embedded Algorithms). The system can thus monitor

RY/ BY to determine whether the reset operation is

complete. If RESET is asserted when a program or erase

operation is not executing (RY/ BY pin is “1”), the reset

operation is completed within a time of tREADY (not during

Embedded Algorithms). The system can read data tRH after

the RESET pin return to VIH.

Refer to the AC Characteristics tables for RESET

parameters and diagram.

Output Disable Mode

When the OE input is at VIH, output from the device is

disabled. The output pins are placed in the high impedance

state.
