ADVANCE INFORMATION GENERAL DESCRIPTION The Am29LV102B is a single power supply, 2 Mbit, 3.0 Volt-only Flash memory device organized as 262,144 bytes. The data appears on DQ0-DQ7. The device is available in 32-pin PLCC and 32-pin TSOP packages. All read, erase, and program operations are accomplished using only a single power supply. The device can also be programmed in standard EPROM programmers. The device offers access times of 55, 70, 90, and 120 ns allowing high speed microprocessors to operate without wait states. To eliminate bus contention, the device has separate control pins—chip enable (CE#), write enable (WE#), and output enable (OE#)—to control normal read and write operations. The device requires only a single power supply (2.7 V–3.6V) for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. The device is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine that controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occurs by executing the program command sequence. This initiates the E mbedded Program algorithm—an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. The Unlock Bypass mode facilitates faster programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase algorithm—an internal algorithm that automatically preprograms the array (if it is not already programmed) before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. The host system can detect whether a program or erase operation is complete by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This is achieved via programming equipment. The Erase Suspend feature enables the user to put erase on hold for any period of time to read data from, or program data to, any sector that is not selected for erasure. True background erase can thus be achieved. The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters the a utomatic sleep mode. The system can also place the device into the standby mode. Power consumption is greatly reduced in both these modes. AMD’s Flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron injection. 2 Am29LV102B 2/9/98 ADVANCE INFORMATION PRODUCT SELECTOR GUIDE Family Part Number Speed Options Regulated Voltage Range: VCC =3.0–3.6 V Full Voltage Range: VCC = 2.7–3.6 V Max access time, ns (tACC) Max CE# access time, ns (tCE) Max OE# access time, ns (tOE) 55 55 30 -55R -70 70 70 30 -90 90 90 30 -120 120 120 35 Am29LV102B Note: See “AC Characteristics” for full specifications.
