Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

5.0

Maximum Ratings and Operating Conditions

5.1

Absolute Maximum Ratings

Warning:

Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent

damage. These are stress ratings only.

5.2

Operating Conditions

Warning:

Operations beyond the “Operating Conditions” is not recommended and extended

exposure beyond the “Operating Conditions” may affect device reliability.

5.3

Power-Up/Down

This section provides an overview of system level considerations with regards to the

flash device. It includes a brief description of power-up/down sequence and decoupling

design considerations.

5.3.1

Power-Up/Down Sequence

To prevent conditions that could result in spurious program or erase operations, the

power-up/power-down sequence shown in Table 6 is recommended. For DC voltage

characteristics refer to Table 8. Note that each power supply must reach its minimum

voltage range before applying/removing the next supply voltage.

NOTICE: This document contains information available at the time of its release. The specifications are subject to change without

notice. Verify with your local Numonyx sales office that you have the latest datasheet before finalizing a design.

Notes:

Voltage is referenced to VSS. During infrequent non-periodic transitions, the voltage potential between VSS and input/

output pins may undershoot to –2.0 V for periods < 20 ns or overshoot to VCCQ (max) + 2.0 V for periods < 20 ns.

During infrequent non-periodic transitions, the voltage potential between VCC and the supplies may undershoot to –2.0

V for periods < 20 ns or VSUPPLY (max) + 2.0 V for periods < 20 ns.

Output shorted for less than one second. No more than one output pin/ball can be shorted at a time.
