NOTE: NOT ALL CMOS CHIPS ARE THE SAME INTERNALLY. THEY MAY HAVE THE SAME SPECIFICATIONS (ie 2M-bit 256k x 8-bit) BUT CAN HAVE DIFFERENT PIN LAYOUTS OR STORE DATA IN DIFFERENT AREAS OF THE CHIP CAUSING THEM NOT TO WORK CORRECTLY (no boot, beep codes, or failed 2nd re-boot) FOR YOUR MOTHERBOARD. ALWAYS TRY TO REPLACE YOUR CMOS CHIP WITH THE EXACT SAME MANUFACTURE AND PART NUMBER AS THE ORGINAL CHIP OTHERWISE YOUR TAKING A REAL GAMBLE.

DETAILED CHIP SPECIFICATIONS .PDF GENERAL DESCRIPTION

The AT29C020 is a 5-volt-only in-system Flash programmable and erasable read-only memory (PEROM). Its 2 megabits of memory is organized as 262,144 bytes. Manu factured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 220 mW over the industrial temperature range. When the device is deselected, the CMOS standby current is less than 300 µA. 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)– 1024 Sectors (256 Bytes/Sector)– Internal Address and Data Latches for 256 Bytes• Internal Program Control and Timer• Hardware and Software Data Protection• Two 8K Bytes Boot Blocks with Lockout• Fast Sector Program Cycle Time – 10 ms• DATAPolling for End of Program Detection• Low Power Dissipation– 40 mA Active Current– 300 µA CMOS Standby Current• Typical Endurance > 10,000 Cycles• Single 5V ±10% Supply• CMOS and TTL Compatible Inputs and Outputs• Green (Pb/Halide-free) Packaging Option
