Frequently Asked Questions
How much program memory and RAM does PIC16C58B-40/SO have and is that sufficient for a simple state machine?
PIC16C58B-40/SO provides 3 KB of OTP program memory and 73 bytes of data RAM. For simple state machines controlling a few GPIO outputs based on input signals, 3 KB of instruction space easily holds hundreds of lines of assembly or a compact C routine, and 73 bytes of RAM is adequate for a handful of variables and a shallow call stack.
At what maximum clock frequency can PIC16C58B-40/SO run and how does that compare to slower PIC variants?
PIC16C58B-40/SO runs at up to 40 MHz, which is the maximum frequency for the -40 speed-grade variant. At 40 MHz and the PIC16 architecture executing most instructions in a single 4-clock cycle, effective throughput reaches 10 million instructions per second, compared to 4 MIPS for a slower 16 MHz variant.
Does PIC16C58B-40/SO include an ADC and what input types is it best suited for?
PIC16C58B-40/SO does not include an ADC, so it handles only digital signals through its 12 I/O pins. It is best suited for applications with digital sensor inputs, pushbutton switches, relay drivers, or PWM-based outputs where all required measurements are performed externally or represented as on/off logic states rather than analog voltage levels.
In what package does PIC16C58B-40/SO come and how does that benefit PCB assembly?
PIC16C58B-40/SO is packaged in a standard SOIC small outline package, which is compatible with automated pick-and-place and reflow soldering assembly processes. The SOIC footprint allows visual inspection of solder joints and rework with standard hot-air tools, making it practical for low-to-medium volume PCB production runs.
Is PIC16C58B-40/SO still recommended for new product designs given its introduction date of 1990?
PIC16C58B-40/SO was introduced in 1990 and has a YTEOL (years to end of life) indicator of 3, suggesting it is in a late life cycle phase. For new designs, Microchip's current PIC16F series offers the same 8-bit architecture with added flash memory, ADC inputs, and enhanced peripherals at similar pin counts, providing a more sustainable long-term supply and feature roadmap.
