AM29LV004B-90REE

The AM29LV004B-90REE is an 4 Megabit (512 K x 8-Bit)CMOS 3.0 Volt-only Boot Sector Flash Memory.It is offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7DQ0.This device requires only a single,3.0 volt VCC supply to perform read, program,and erase  operations.A standard EPROM programmer can also be used to program and erase the device.

Features of the AM29LV004B-90REE are:(1)Single power supply operationFull voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications Regulated voltage range: 3.0 to 3.6 volt read and write operations and for compatibility with high performance 3.3 volt microprocessors;(2)High performance:Full voltage range: access times as fast as 100ns Regulated voltage range: access times as fast as 90 ns;(3)Ultra Low power consumption (typical values at 5 MHz):200nA standby mode current10mA read current20mA program/erase current200 nA Automatic Sleep mode current;(4)Flexible sector architecture:One 16 Kbyte,two 8 Kbyte,one 32 Kbyte,and seven 64 Kbyte sectorsSupports full chip erase Sector Protection features..A hardware method of locking a sector to prevent any program or erase operations within that sector,they can be locked via programming equipment Temporary Sector Unprotect feature allows code changes in previously locked sectors;(5)Top or bottom boot block configurations available;(6)Embedded Algorithms: Embedded Erase algorithm automatically preprograms and erases the entire chip or any combination of designated sectorsEmbedded Program algorithm automatically writes and verifies data at specified addresses;(7) typical 1,000,000 write cycles per sector(100,000cycles minimum guaranteed);(8)Package option:40-pin TSOP32-pin PLCC;(9)Compatibility with JEDEC standards:Pinout and software compatible with single-power supply FlashSuperior inadvertent write protection;(10)Data# Polling and toggle bits:Provides a software method of detecting program or erase operation completion;(11)Erase Suspend/Erase Resume: Suspends an erase operation to read data from, or program data to, a sector that is not being erased,then resumes the erase operation;(12)Hardware reset pin (RESET#): Hardware method to reset the device to reading array data (not available on Am29F002NB);(13)Erase Suspend/Erase Resume:Provides a hardware method of detecting program or erase cycle completion.

The absolute maximum ratings of the AM29LV004B-90REE can be summarized as:(1)Storage Temperature Plastic Packages:65 to +150;(2)Ambient Temperature with Power Applied:65 to +125;(3)Voltage with Respect to Ground:V_CC(Note 1)..0.5V to +4.0VA9, OE#,and RESET#(Note 2)..0.5V to +12.5VAll other pins(Note 1)..0.5V to V_CC+0.5V;(4)Output Short Circuit Current(Note 3):200mA.Notes:
1.Minimum DC voltage on input or I/O pins is -0.5V. During voltage transitions,input or I/O pins may overshoot V_SS to2.0V for periods of up to 20 ns. See Figure 6.Maximum DC voltage on input or I/O pins is V_CC +0.5 V.During voltage transitions,input or I/O pins may overshoot to V_CC+2.0 V for periods up to 20 ns. See Figure 7.
2.   Minimum DC input voltage on pins A9, OE#, and RESET# is 0.5 V. During voltage transitions, A9, OE#, and RESET# may overshoot VSS to 2.0V for periods of up to 20ns.See Figure 6.Maximum DC input voltage on pin A is +12.5V which may overshoot to +13.5V for periods up to 20 ns(RESET# is not available on Am29F002NB)
3.No more than one output may be shorted to ground at a time.Duration of the short circuit should not be greater than one second.
Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this data sheet is not implied. Exposure of the device to absolute maximum rating conditions for extended periods may affect device reliability.
