Now over 1,300 items in our Store! AT29C020-12TC Atmel $6.95 each The following spec sheet is provided by Atmel and may cover several different versions and/or products. This listing is only for the item pictured and listed in the heading. Fast Read Access Time - 120 ns 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 8 KB Boot Blocks with Lockout · Fast Sector Program Cycle Time - 10 ms · DATA Polling for End of Program Detection · Typical Endurance > 10,000 Cycles · CMOS and TTL Compatible Inputs and Outputs · Commercial and Industrial Temperature Ranges 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. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 90 ns with power dissipation of just 220 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 mA. Device endurance is such that any sector can typically be written to in excess of 10,000 times. To allow for simple in-system reprogrammability, the AT29C020 does not require high input voltages for programming. Five-volt-only commands determine the operation of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29C020 is performed on a sector basis; 256-bytes of data are loaded into the device and then simultaneously programmed. During a reprogram cycle, the address locations and 256- bytes of data are internally latched, freeing the address and data bus for other operations. Following the initiation of a program cycle, the device will automatically erase the sector and then program the latched data using an internal control timer. The end of a program cycle can be detected by DATA polling of I/O7. Once the end of a program cycle has been detected, a new access for a read or program can begin.
