AMD’s Flash mem- ories offer the most cost-effective and reliable read/ write n on -vo latile ran dom ac cess memor y. The Am28F512 is packaged in 32-pin PDIP, PLCC, and TSOP versions. It is designed to be reprogrammed and erased in-system or in standard EPROM pro- grammers. The Am28F512 is erased when shipped from the factory. The standard Am28F512 offers access times as fast as 70 ns, allowing operation of high-speed microproces- sors without wait states. To eliminate bus contention, the Am28F512 has separate chip enable (CE#) and output enable (OE#) controls. AMD’s Flash memories augment EPROM functionality with in-circuit electrical erasure and programming. The Am28F512 uses a command register to manage this functionality, while maintaining a standard JEDEC Flash Standard 32-pin pinout. The command register allows for 100% TTL level control inputs and fixed power supply levels during erase and programming. AMD’s Flash technology reliably stores memory con- tents even after 10,000 erase and program cycles. The AMD cell is designed to optimize the erase and pro- gramming mechanisms. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling. The Am28F512 uses a 12.0 V ± 5% VPP high voltage input to perform the Flasherase and Flashrite algorithms. The highest degree of latch-up protection is achieved with AMD’s proprietary non-epi process. Latch-up pro- tection is provided for stresses up to 100 mA on ad- dress and data pins from -1 V to VCC +1 V. The Am28F512 is byte programmable using 10 ms pro- gramming pulses in accordance with AMD’s Flashrite programming algorithm. The typical room temperature programming time of the Am28F512 is one second. The entire chip is bulk erased using 10 ms erase pulses according to AMD’s Flasherase algorithm. Typical era- sure at room temperature is accomplished in less than one second. The windowed package and the 15-20 minutes required for EPROM erasure using ultra-violet light are eliminated. Commands are written to the command register using standard microprocessor write timings. Register con- tents serve as inputs to an internal state-machine which controls the erase and programming circuitry. During |
