The PIC16C923-04/L is a PIC® 8-bit microcontroller IC manufactured by Microchip. It is an 8-bit device with a maximum clock frequency of 4MHz and a total of 7KB (4K x 14) of One-Time Programmable (OTP) memory. It comes in a 68-pin leaded plastic chip carrier (PLCC) package, which measures 24.23x24.23 mm. This device features several integrated peripheral functions such as an ADC, Timers, Port I/O, and EUSART (an enhanced UART) which enables robust serial communications. It also features power saving sleep modes, low power options, wide operating voltage range (2.0-5.5V), an industry standard instruction set, and advanced interrupt capabilities. These features make the PIC16C923-04/L an ideal choice for a variety of low-cost applications, including automotive, telecom, LCD display interfaces, and motor control.
