Microchip Technology, Inc. 256Kb (32-Kbit x 8) Low-Voltage OTP EPROM AT27LV256A

The Microchip AT27LV256A is a high-performance, low-power, low-voltage 256-Kbit One Time Programmable EPROM organized as 32-Kbit x 8. Requiring a single power supply in the range of 3.0V to 3.6V in normal read mode operation any byte can be accessed in less than 90 ns. Typical power consumption of only 18 mW at 5 MHz and VCC = 3.3V, the AT27LV256A consumes less than one-fifth the power of a standard, 5V EPROM. Standby mode supply current is typically less than 1 μA at 3.3V making it ideal for fast, portable systems using battery power. Additional Features 256-Kbit (32-Kbit x 8) Dual voltage range operation Low voltage, 3.0V to 3.6V, or Standard power supply range, 5V +/-10% Low-power CMOS operation 20 μA max standby (less than 1 μA, typical) for VCC = 3.6V 29 mW max active at 5 MHz for VCC = 3.6V Parallel Interface 90 ns access time 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 Integrated product identification code Industrial Temperature Range: -40°C to 85°C Available in Green (Pb/Halide-free) Packaging Only 32-lead, Plastic J-leaded Chip Carrier (PLCC)
