AT49F8192A-90TI Datasheet

The AT49F008A T and AT49F8192A T are 5-volt, 8-megabit Flash memories organized as 1,048,576 words of 8 bits each or 512K words of 16 bits each. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 90 ns with power dissipation of just 275 mW. When deselected, the CMOS standby current is less than 100 µA.

Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 90 ns with power dissipation of just 275 mW. When deselected, the CMOS standby current is less than 100 µA. The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available the AT49F008A/8192A locates the boot block at lowest order addresses “bottom boot” the AT49F008AT/8192AT locates it at highest order addresses “top boot” . To allow for simple in-system reprogrammability, the AT49F008A T /8192A T does not require high-input voltages for programming. Reading data out of the device is similar to reading from an EPROM it has standard CE, OE and WE inputs to avoid bus contention. Reprogramming the AT49F008A T /8192A T is performed by first erasing a block of data and then programming on a byte-by-byte or word-by-word basis.

The device is erased by executing the Erase command sequence the device internally controls the erase operation. The memory is divided into four blocks for erase operations. There are two 4K word parameter block sections the boot block, and the main memory array block. The typical number of program and erase cycles is in excess of 10,000 cycles. The optional 8K word boot block section includes a reprogramming lockout feature to provide data integrity. This feature is enabled by a command sequence. Once the boot block programming lockout feature is enabled, the data in the boot block cannot be changed when input levels of volts or less are used. The boot sector is designed to contain user secure code. For the AT49F8192A T , the BYTE pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE pin is set at a logic “1” or left open, the device is in word configuration, I/O0 - I/O15 are active and controlled by CE and OE. If the BYTE pin is set at logic “0”, the device is in byte configuration, and only data I/O pins I/O0 - I/O7 are active and controlled by CE and OE. The data I/O pins I/O8 - I/O14 are tristated and the I/O15 pin is used as an input for the LSB A-1 address function. 2 AT49F008A T /8192A T AT49F008A T Block Diagram AT49F008A T /8192A T VCC GND OE WE CE RESET ADDRESS INPUTS CONTROL LOGIC Y DECODER X DECODER AT49F008A DATA INPUTS/OUTPUTS I/O0 - I/O7 AT49F008A Ordering Information tACC ICC mA Active Standby Ordering Code AT49F008A-70TI AT49F008A-90TI AT49F8192A T Ordering Information tACC ICC mA Active Standby Ordering Code AT49F8192A-70TI AT49F8192AT-70TI AT49F8192A-90TI AT49F8192AT-90RI AT49F8192AT-90TI Package 40T Operation Range Industrial -40° to 85°C Industrial -40° to 85°C Package 48T 44R 48T Operation Range Industrial -40° to 85°C Industrial -40° to 85°C Industrial -40° to 85°C Industrial -40° to 85°C Package Type 44-lead, Wide, Plastic Gull Wing Small Outline Package SOIC 40-lead, Plastic Thin Small Outline Package TSOP 48-lead, Plastic Thin Small Outline Package TSOP 14 AT49F008A T /8192A T Packaging Information 44R SOIC AT49F008A T /8192A T Dimensions in Millimeters and Inches .
