Features Fast read access time – 45ns Low-power CMOS operation – 100µA max standby – 20mA max active at 5MHz JEDEC standard packages – 28-lead PDIP – 32-lead PLCC 5V± 10% supply High-reliability CMOS technology – 2,000V ESD protection – 200mA latchup immunity Rapid programming algorithm – 100µs/byte (typical) CMOS- and TTL-compatible inputs and outputs Integrated product identification code Industrial and automotive temperature ranges Green (Pb/halide-free) packaging option 512K (64K x 8) One-time Programmable, Read-only Memory Atmel AT27C512R 1. Description The Atmel® AT27C512R is a low-power, high-performance, 524,288-bit, one-time programmable, read-only memory (OTP EPROM) organized as 64K by 8 bits. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 45ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. The Atmel scal...
