Description

The ST62E28CF1 is an electronic component model in the IC Chips product category. It is a low-cost microcontroller that belongs to the ST62xx 8-bit HCMOS family. This family of microcontrollers is designed for low to medium complexity applications. The ST62E28CF1 features a common core surrounded by various on-chip peripherals. It operates within a supply voltage range of 3.0 to 6.0V and has a maximum clock frequency of 8 MHz. The temperature range for operation is -40 to +125°C. It offers multiple operating modes, 5 interrupt vectors, and has a look-up table capability in program memory. The ST62E28CF1 also provides options for user programmable data storage and has 192 bytes of data RAM. With 20 fully programmable I/O pins, it supports various configurations such as input with pull-up resistor, input without pull-up resistor, input with interrupt generation, open-drain or push-pull output, and analog input. Additionally, it has 8 I/O lines that can sink up to 20mA, allowing direct driving of LEDs or TRIACs. Other features include an 8-bit timer/counter, an 8-bit auto-reload timer, a digital watchdog, an 8-bit A/D Converter with 12 analog inputs, an 8-bit asynchronous peripheral interface (UART), and an 8-bit synchronous peripheral interface (SPI). The on-chip clock oscillator can be driven by a Quartz Crystal, Ceramic resonator, or an RC network. It also incorporates an oscillator safe guard and a low voltage detector for safe reset. Furthermore, the ST62E28CF1 has one external Non-Maskable Interrupt and is compatible with the ST623x-EMU2 Emulation and Development System.
