1 / 10 page 1 PLCC, Top View Features • Fast Read Access Time - 90 ns • Dual Voltage Range Operation – Unregulated Battery Power Supply Range, 2.7V to 3.6V or Standard 5V ± 10% Supply Range • Compatible with JEDEC Standard AT27C020 • Low Power CMOS Operation –20 µA max. (less than 1 µA typical) Standby for V CC = 3.6V – 29 mW max. Active at 5 MHz for V CC = 3.6V • Wide Selection of JEDEC Standard Packages – 32-Lead PLCC – 32-Lead TSOP (8 x 20mm) – 32-Lead VSOP (8 x 14mm) – 42-Ball CBGA (8 x 8mm) • High Reliability CMOS Technology – 2,000V ESD Protection – 200 mA Latchup Immunity • Rapid™ Programming Algorithm - 100 µs/byte (typical) • CMOS and TTL Compatible Inputs and Outputs – JEDEC Standard for LVTTL and LVBO • Integrated Product Identification Code • Commercial and Industrial Temperature Ranges Description The AT27BV020 is a high-performance, low-power, low-voltage 2,097,152-bit one- time programmable read only memory (OTP EPROM) organized as 256K by 8 bits. It requires only one supply in the range of 2.7 to 3.6V in normal read mode operation, making it ideal for fast, portable systems using either regulated or unregulated battery power.
