Frequently Asked Questions - PIC16CR58B Microchip
What is the PIC16CR58B?
The PIC16CR58B is an 8-bit microcontroller from Microchip, featuring 512x12 ROM program memory and 25 bytes RAM.
What voltage does the PIC16CR58B require?
It operates from 2.5V to 5.5V, making it suitable for battery-powered applications.
How do I program the PIC16CR58B?
The PIC16CR58B is a ROM-based device, programmed by Microchip during manufacturing. For prototyping, use the OTP version (PIC16C58B).
What development tools are compatible?
Use MPLAB X IDE with a programmer like PICkit or ICD series for compatible PIC16C5X devices.
What is the maximum clock speed?
The maximum clock frequency is 4 MHz, using an external crystal or RC oscillator.
How many I/O pins does it have?
It has 12 I/O pins, arranged in two ports (PortA and PortB).
Does it have an internal oscillator?
No, it requires an external clock source such as a crystal, ceramic resonator, or RC circuit.
Can I use interrupts?
Yes, but only internal interrupts from the timer and wake-up from sleep. No external interrupt pins.
How do I reset the device?
Apply a low pulse to the MCLR pin (master clear) to reset. An external pull-up resistor is recommended.
What is the power consumption?
Typical current is 2 mA at 4 MHz and 5V. Sleep mode reduces consumption to < 1 µA.
