ST62T01CM3 [STMicroelectronics]

ST62T01CM3 Description

The ST62T01CM3 device is a low-cost member of the ST62xx 8-bit HCMOS microcontroller family, which is intended for applications with low to medium complexity. A common core is surrounded by a number of on-chip peripherals, which forms the basis for all ST62xx devices.

The ST62T01CM3 is the erasable EPROM version of the ST62T00C, T01, and T03C target devices, as well as the corresponding ST6200C, 01C, and 03C ROM devices, which may be utilized during the development phase.

Devices using OTP and EPROM have the same functionality. OTP devices are the best option in a variety of applications when frequent code updates, various code versions, or last-minute programmability are required since they provide all the benefits of user programmability at a cheap cost.

The OTP/EPROM versions' programmable option bytes are defined in the ROM option list, and the ROM-based versions provide the same capability by selecting those options.

The Factory Advanced Service Technique ROM (FASTROM) variants of the ST62T00C, T01 and T03C OTP devices are designated ST62P00C, P01C, and P03C.

They provide the same capabilities as OTP devices but do not require customer programming.

These small, inexpensive devices have an 8-bit counter, a 7-bit programmable Prescaler, an 8-bit A/D converter, four analog inputs, and a digital watchdog timer, making them suitable for a variety of industrial, appliance, and automotive applications.
