TB026

Many applications require the microcontroller to calculate a checksum on the program memory to determine if the contents have been corrupted. Until now, the only family of PICmicro® microcontrollers to have the capability to read from program memory are the TB026 devices. The TB026 devices are the first 14-bit core PICmicro microcontrollers that are able to access program memory in the same fashion as used with data EEPROM memory. These devices are FLASH extensions of the popular TB026 family. Table 1 shows a comparison between the two PICmicro microcontroller families.
