Microchip Technology, Inc. Microcontrollers PIC12C508AT-04I/SM

The PIC12C508AT-04I/SM is an 8-bit CMOS microcontroller featuring a high-performance RISC CPU with only 33 single-word instructions, all of which execute in a single cycle except for program branches, which take two cycles. It operates at a clock speed of up to 4 MHz, with a 1 ms instruction cycle. The device includes 512 x 12 bits of program memory and 25 bytes of EEPROM data memory, with a data retention period exceeding 40 years. Key features include an internal 4 MHz RC oscillator with programmable calibration, in-circuit serial programming capability, and a variety of peripheral functions such as an 8-bit real-time clock/counter with a programmable prescaler, Power-On Reset (POR), Device Reset Timer (DRT), and Watchdog Timer (WDT). The microcontroller supports multiple oscillator options, including internal and external configurations. The PIC12C508AT-04I/SM is designed for low power consumption, with typical operating currents of less than 2 mA at 5V and 4 MHz, and standby currents below 1 mA. It operates over a wide voltage range of 2.5V to 5.5V and is suitable for commercial, industrial, and extended temperature ranges. This microcontroller is ideal for applications requiring compact, efficient processing capabilities in a variety of environments.
