Frequently Asked Questions
How much Flash and RAM does PIC16F15345-I/SO provide, and is it enough for a typical sensor hub firmware?
PIC16F15345-I/SO includes 14 KB of Flash program memory and 1 KB of SRAM data memory. For a typical sensor hub reading 4 to 8 sensor channels, filtering data, and transmitting over UART at 115200 bps, 14 KB Flash is generally sufficient, though designs with complex state machines or large lookup tables may need a PIC16 variant with 28 KB or more.
What clock frequency does PIC16F15345-I/SO support, and how does this affect PWM resolution in a motor control design?
The device operates at up to 32 MHz, which gives the 4 PWM modules a resolution of up to 10 bits at 31 kHz PWM frequency or approximately 8 bits at 125 kHz. For brushed DC motor control at audio frequencies, 32 MHz provides sufficient resolution to avoid audible PWM ripple while maintaining adequate current control bandwidth.
What serial communication interfaces are available on PIC16F15345-I/SO, and can it run UART and SPI simultaneously?
PIC16F15345-I/SO includes 2 independent EUSART modules, plus one SPI and one I2C interface sharing the same MSSP peripheral. This allows the device to maintain a UART debug console on one EUSART while running a second UART for sensor communication, plus SPI or I2C for a display or external memory, all concurrently.
Is PIC16F15345-I/SO a good fit for replacing older PIC16F877A designs, and what migration effort is needed?
PIC16F15345-I/SO offers more Flash (14 KB vs 8 KB), additional peripherals such as CLC and DAC, and lower operating voltage compared to PIC16F877A. However, the pin count drops from 40 pins to 20 pins, so designs relying on more than 14 I/O lines will need a larger package variant such as PIC16F15355 in SOIC-28 or QFN-28.
