Frequently Asked Questions
How much flash and EEPROM memory does the PIC16LF628A provide?
The PIC16LF628A includes 3.5 KB of flash program memory and 128 bytes of data EEPROM, plus 224 bytes of SRAM. This combination supports moderately complex firmware with persistent parameter storage, making it well suited for sensor nodes, calibration data, and small control applications running at up to 20 MHz.
Which supply voltage range allows the PIC16LF628A to operate reliably in battery-powered designs?
The PIC16LF628A operates from 1.8 V to 3.6 V, which directly matches single lithium-ion cell or two AAA alkaline cell supplies. This wide low-voltage range extends battery life in portable designs such as wireless sensors, remote controls, and handheld meters where current draw must stay below the device's rated active current.
Can the PIC16LF628A drive PWM outputs for motor or LED control?
Yes. The on-chip Capture/Compare/PWM (CCP) module generates PWM signals with up to 10-bit resolution at frequencies compatible with small DC motor controllers and LED dimmers. Combined with 16 I/O pins and a 20 MHz clock, the device handles typical duty-cycle control loops without requiring external PWM driver ICs.
What serial communication interface is available on the PIC16LF628A?
The PIC16LF628A integrates a full USART module supporting asynchronous RS-232-style communication and synchronous SPI-master mode. Operating at 20 MHz, it achieves standard baud rates up to 115,200 bps for UART links. This makes the device suitable for data-logging systems, GPS module interfaces, and host-to-peripheral command channels.
How does the SOIC-18 package of the PIC16LF628A compare in board footprint to a DIP-18 variant?
The SOIC-18 package measures approximately 11.6 mm × 7.5 mm with a 1.27 mm lead pitch, occupying roughly 60% less PCB area than the 18-pin 2.54 mm pitch DIP package. This smaller footprint benefits compact SMT designs while retaining all 16 I/O pins, dual comparators, and the CCP module available on the DIP-18 version.
