DESCRIPTION

The CAT28F020 is a high speed 256K x 8-bit electrically erasable and reprogrammable Flash memory ideally suited for applications requiring in-system or after-sale code updates. Electrical erasure of the full memory contents is achieved typically within 0.5 second.

FEATURES

■ Fast read access time: 90/120 ns

■ Low power CMOS dissipation:

– Active: 30 mA max (CMOS/TTL levels)

– Standby: 1 mA max (TTL levels)

– Standby: 100 μA max (CMOS levels)

■ High speed programming:

– 10 μs per byte

– 4 seconds typical chip program

■ 0.5 seconds typical chip-erase

■ 12.0V ± 5 programming and erase voltage

■ Commercial, industrial and automotive temperature ranges

■ Stop timer for program/erase

■ On-chip address and data latches

■ JEDEC standard pinouts:

– 32-pin DIP

– 32-pin PLCC

– 32-pin TSOP (8 x 20)

■ 100,000 program/erase cycles

■ 10 year data retention

■ Electronic signature
