What are the key features of PIC16F636-I/ML?
- 3.5 KB Flash and 256 bytes EEPROM in an ultra-compact VQFN-16 package, enabling firmware plus non-volatile data storage in under 4 mm × 4 mm footprint
- Operates from as low as 2 V supply at 4 MHz, making it ideal for single-cell or 2-cell alkaline battery-powered designs
- Up to 20 MHz clock speed with PIC16 core provides efficient code execution for timer-based, communication, and control tasks
What is PIC16F636-I/ML used for?
The PIC16F636-I/ML is ideal for low-power consumer and IoT devices such as smart keychain remotes, wireless sensor nodes, and portable medical accessories where the 2 V minimum supply allows the MCU to run down a battery to near-depletion. Its 256 bytes of EEPROM enable persistent parameter storage for device configuration without external memory, and the VQFN-16 package minimizes PCB area in compact wearable or coin-cell powered designs.

Frequently Asked Questions
What is the minimum supply voltage at which the PIC16F636-I/ML can operate, and at what clock speed?
The PIC16F636-I/ML can operate from a minimum supply voltage of 2 V while running at up to 4 MHz. This low-voltage capability allows the MCU to continue functioning near the end of a single-cell alkaline or NiMH battery discharge cycle, extending product runtime compared to devices that require 2.7 V or more to start.
How much non-volatile storage does the PIC16F636-I/ML provide, and how is it typically used?
The device includes 3.5 KB of Flash program memory and 256 bytes of data EEPROM, plus 128 bytes of SRAM. The EEPROM is commonly used to store calibration constants, device serial numbers, usage counters, or user-configurable parameters that must survive power cycling without the cost or complexity of an external serial EEPROM component.
For a coin-cell powered remote-control design, why is the PIC16F636-I/ML a strong candidate versus a 28-pin PIC16 device?
The VQFN-16 package occupies roughly 4 mm × 4 mm of PCB area compared to a 28-pin SOIC or DIP that can exceed 18 mm in length. Combined with the 2 V operating capability and deep-sleep modes drawing microampere-level quiescent current, the PIC16F636-I/ML fits into a coin-cell remote PCB that must last over 12 months on a CR2032 cell rated at 220 mAh.
Does the PIC16F636-I/ML include an analog-to-digital converter, and what alternatives exist within the PIC16F6xx family?
The PIC16F636-I/ML does not integrate an ADC. For applications requiring analog signal conversion, the PIC16F676 is a pin-compatible alternative that adds an 8-channel 10-bit ADC while maintaining the same 3.5 KB Flash, 256-byte EEPROM, 128-byte RAM, and VQFN-16 footprint, enabling a straightforward board-level swap when sensor-input capability is needed.
