PIC16LCE624-04/SS - 8-bit PIC MCU 1.75KB OTP 4MHz SSOP-20
The Microchip Technology PIC16LCE624-04/SS is an 8-bit PIC microcontroller from the PIC16C family, featuring 1.75 KB (1K x 14) of One-Time Programmable (OTP) program memory, 96 bytes of RAM, and 13 general-purpose I/O pins, all packaged in a 20-pin SSOP (Shrink Small Outline Package). The device operates from a 2.5V to 5.5V supply and supports a maximum clock speed of 4 MHz (the "/04" speed grade), targeting low-power and cost-sensitive embedded designs.
An 8-bit PIC microcontroller (MCU) is a compact, Harvard-architecture computing device built around an 8-bit data path, 14-bit instruction word, and integrated peripherals such as timers, comparators, and communication interfaces. Within the broader semiconductor hierarchy, MCUs sit between general-purpose microprocessors and ASICs: they embed CPU, memory, and I/O on a single die, enabling deterministic real-time control in embedded systems. The PIC16C family is one of Microchip's foundational mid-range MCU lines, predating the flash-based PIC16F series and offering OTP and ROM variants for high-volume, cost-sensitive products.
Key features of the PIC16LCE624-04/SS include an internal oscillator option, an integrated analog comparator, a capture/compare/PWM (CCP) module, a watchdog timer with its own on-chip RC oscillator, and in-circuit serial programming (ICSP) via two pins. The device's low-power "L" variant supports battery-friendly operation, and the "E" designation (not present on this part) would indicate the extended-temperature grade; this MPN is the commercial-temperature grade (0°C to +70°C). The SSOP-20 footprint enables compact PCB layouts while still providing sufficient I/O for typical sensor, switch, and indicator-control applications.
The PIC16LCE624-04/SS architecture uses a RISC instruction set with only 35 single-word instructions, simplifying code generation and easing firmware development. Its 14-bit instruction width delivers reasonable code density for the era's typical control loops, and the Harvard bus allows simultaneous instruction fetch and data access. Compared to flash-based successors, OTP memory requires a programmed device to be discarded and replaced if firmware changes are needed, which is acceptable in mature, high-volume production where code is finalized.
Typical applications include consumer appliance control (washing machines, microwave ovens, coffee makers), simple industrial timers and counters, remote-control transmitters, low-end security keypads, sensor interface boards, and LED display drivers. The combination of analog comparator, timer, and PWM resources enables direct motor-control or lighting-control loops without external glue logic.
When designing with this MCU, allocate the I/O budget carefully: 13 usable I/O pins must support all digital I/O plus any analog comparator or ICSP functions, which can reserve two additional pins during programming. The OTP memory constraint means firmware must be fully validated in development before committing to production programming, and an engineering stock of pre-programmed parts should be planned accordingly.
