5 / 72 page 5/72 ST62T45B/E45B 1 GENERAL DESCRIPTION 1.1 INTRODUCTION The ST62T45B and ST62E45B devices are low cost members of the ST62xx 8-bit HCMOS family of microcontrollers, which are targeted at low to medium complexity applications. All ST62xx de- vices are based on a building block approach: a common core is surrounded by a number of on- chip peripherals. The ST62E45B is the erasable EPROM version of the ST62T45B device, which may be used to em- ulate the ST62T45B device, as well as the respec- tive ST6245B ROM devices. Figure 1.
