What are the key features of PIC16LC63A-04I/SO?
- 8-bit PIC16 CMOS core running at up to 4 MHz for deterministic low-speed control
- 2 V to 6 V supply range enabling use with diverse power sources including 3-cell alkaline batteries
- Integrated USART, SPI, and I2C for multi-protocol serial communication without external chips
- 28 I/O pins in a 28-pin SOIC package for compact PCB layouts with ample connectivity
- 192 B RAM and 4 KB program Flash supporting modest embedded control firmware
What is PIC16LC63A-04I/SO used for?
The PIC16LC63A-04I/SO is suitable for cost-effective consumer appliances, remote controls, and simple industrial control panels that require USART or I2C communication at modest 4 MHz processing speed. Its 2 V to 6 V supply tolerance accommodates direct operation from 2-cell to 4-cell alkaline or NiMH battery packs without a voltage regulator. The device also fits legacy-compatible designs in HVAC controllers, smart card readers, and keypad interfaces where the well-established PIC16 instruction set simplifies migration from older production firmware.

Frequently Asked Questions
What is the maximum clock frequency of the PIC16LC63A-04I/SO, and how does it affect real-time control responsiveness?
The PIC16LC63A-04I/SO runs at a maximum clock frequency of 4 MHz, executing instructions at 1 MIPS since the PIC16 architecture uses a 4-clock instruction cycle. This throughput is sufficient for deterministic control tasks such as keypad scanning, serial framing at 9600 baud USART communication, and simple state-machine logic, while keeping active current consumption well below 5 mA from a 5 V supply.
Which serial communication interfaces are built into the PIC16LC63A-04I/SO, and what protocols can they support?
The PIC16LC63A-04I/SO integrates a hardware USART for RS-232 or RS-485 communication, an MSSP module that supports both SPI (up to 1 Mbps at 4 MHz) and I2C (100 kHz standard mode), and a Parallel Slave Port for direct 8-bit data bus connections. This combination lets a single 28-pin device act as a USART gateway, an I2C sensor hub, or an SPI peripheral controller without any external serial bridge IC.
For a legacy maintenance project still using PIC16LC63A-04I/SO, what supply voltage flexibility does the LC-grade device offer compared to the standard C-grade?
The LC-grade PIC16LC63A-04I/SO operates from 2 V to 6 V, wider than the standard PIC16C63A's typical 4.0 V to 6.0 V range, making it easier to source from 3-cell NiMH packs at roughly 3.6 V or from 2-AA alkaline stacks at 2.4 V to 3 V near end of discharge. This broader tolerance allows the same firmware to run in battery-primary designs without adding a boost regulator, reducing BOM cost by one to two components.
