0V · CMOS and TTL compatible I/O · Low power consumption - Active: 30mA max.
- Standby: 1mA typ.
· 256K´8-bit organization · Fast read access time: 70ns · Fast programming algorithm · Programming time 75ms typ.
· Two line controls (OE and CE) · Standard product identification code · Commercial temperature range (0°C to +70°C) · 32-pin DIP/SOP/PLCC package General Description The HT27C020 chip family is a low-power, 2048K (2,097,152) bits, +5V electrically one-time programmable (OTP) read-only memories (EPROM).
Organized into 256K words with 8 bits per word, it features a fast single address location programming, typically at 75ms per byte.
Any byte can be accessed in less than 70ns with respect to Spec.
This eliminates the need for WAIT states in high-performance microprocess...
