DescriptionThe AT29C256-90PI is one member of the AT29C256 family which designed as one kind of five-volt-only in-system Flash programmable and erasable read only memory (PEROM).Memory of it is organized as 32,768 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.
Features of the AT29C256-90PI are:(1)fast read access time-70 ns;(2)5-volt only reprogramming;(3)page program operation:single cycle reprogram (erase and program) and internal address and data latches for 64 bytes;(4)internal program control and timer;(5)hardware and software data protection;(6)fast program cycle times:page (64 byte) program time-10 ms and chip erase time-10 ms;(7)DATA polling for end of program detection;(8)low-power dissipation: 50 mA active current and 300 A CMOS standby current;(9)typical endurance > 10,000 cycles;(10)single 5V±10% supply;(11)CMOS and TTL compatible inputs and outputs;(12)commercial and industrial temperature ranges.
The absolute maximum ratings of the AT29C256-90PI can be summarized as:(1)temperature under bias:-55°C to +125°C;(2)storage temperature:-65°C to +150°C;(3)all input voltages (including NC pins) with respect to ground:-0.6V to +6.25V;(4)all output voltages with respect to ground:-0.6V to VCC+0.6V;(5)voltage on OE with respect to ground:-0.6V to +13.5 V.If you want to know more information such as the electrical characteristics about the AT29C256-90PI,please download the datasheet in www.seekic.com or www.chinaicmart.com .
