Frequently Asked Questions - PIC16C770 Microchip
What development tools are needed to program the PIC16C770?
You need a compatible programmer (e.g., MPLAB ICD 4, PICkit 4) and the MPLAB X IDE with a suitable compiler (e.g., XC8). The device uses ICSP for programming.
Can the PIC16C770 be reprogrammed?
No, the PIC16C770 is an OTP (one-time programmable) device. Once programmed, the code cannot be erased or rewritten. For multiple programming cycles, consider the Flash-based PIC16F7 series.
What is the maximum clock frequency of the PIC16C770?
The maximum external clock frequency is 20 MHz. It also has an internal 4 MHz oscillator.
How many analog inputs does the PIC16C770 have?
It features an 8-channel, 10-bit Analog-to-Digital Converter (ADC) on 8 pins.
What is the operating voltage range for the PIC16C770?
The device operates from 2.5V to 5.5V DC.
Does the PIC16C770 support sleep mode for low power?
Yes, it has a Sleep mode that reduces power consumption to microamps. It can wake up on external interrupt or timer overflow.
How much RAM and ROM does the PIC16C770 have?
It has 128 bytes of RAM and 2K x 14 words of program memory (OTP ROM).
What communication interfaces are available on the PIC16C770?
It includes a Synchronous Serial Port (SSP) supporting SPI mode. No I2C or UART is built-in, but it can be implemented in software.
How many I/O pins are available on the PIC16C770?
It has 16 I/O pins, with some shared with analog and timer functions. Each pin can sink/source up to 25 mA.
Can the PIC16C770 drive LEDs directly?
Yes, each I/O pin can source up to 25 mA, sufficient for driving standard LEDs with appropriate current-limiting resistors.
