Microchip AT29C512-12JI

64K x 8120 нс-40°C ~ 85°C (TC)

Overview

The AT29C512 is a 5-volt only in-system Flash programmable and erasable read only memory (PEROM). Its 512K of memory is organized as 65,536 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 275 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 µA. The device endurance is such that any sector can typically be written to in excess of 10,000 times.

Features • Fast Read Access Time – 70 ns • 5-volt Only Reprogramming • Sector Program Operation – Single Cycle Reprogram (Erase and Program) – 512 Sectors (128 Bytes/Sector) – Internal Address and Data Latches for 128 Bytes • Internal Program Control and Timer • Hardware and Software Data Protection • Fast Sector Program Cycle Time – 10 ms • DATA Polling for End of Program Detection • Low Power Dissipation – 50 mA Active Current – 100 µA CMOS Standby Current • Typical Endurance > 10,000 Cycles • Single 5V ± 10% Supply • CMOS and TTL Compatible Inputs and Outputs • Commercial and Industrial Temperature Ranges
