The 072 by-16 bit 097 152-bit), boot-block flash memory that can be electrically block-erased and reprogrammed. The TMS28F200Axy is organized in a blocked architecture consisting of:

One 16K-byte protected boot block Two 8K-byte parameter blocks One 96K-byte main block One 128K-byte main block

The device can be ordered in five different voltage configurations (see Table 1). Operation 128K-word (16-bit) organization is user-definable. The TMS28F002Axy is offered a 256K-byte organization only. The operation for this device is the same as the TMS28F200Axy and is offered in the same voltage configurations. TMS28F002Axy can be substituted for the byte-wide TMS28F200Axy, with the latter being the generic name for this device family. Embedded program and block-erase functions are fully automated by the on-chip write-state machine (WSM), thereby simplifying these operations and relieving the system microcontroller of these secondary tasks. WSM status can be monitored by an on-chip status register to determine the progress of program / erase tasks. The device features user-selectable block-erasure. The configurations are as follow:

The TMS28F002ASy and the TMS28F200ASy configurations have the auto-select feature that allows alternative read and program / erase voltages. Memory reads can be performed using 3.3-V VCC for optimum power consumption at 5-V VCC, for device performance. Erasing or programming the device can be accomplished with 5-V VPP, which eliminates having to use a 12-V source and / or in-system voltage converters. Alternatively, 12-V VPP operation exists for systems that already have a 12-V power supply, which provides faster programming and erasing times. These configurations are offered in two different temperature ranges: to 70C and to 85C. The TMS28F002AEy and the TMS28F200AEy configurations offer the auto-select feature of the TMS28F200ASy with an extended VCC to a low to 3.6-V range (3-V nominal). Memory reads can be performed using a 3-V VCC, allowing for more efficient power consumption than the 'ASy device.
