Frequently Asked Questions
How much program memory does the PIC16LF84A-04/SO have?
The PIC16LF84A-04/SO contains 1.75 KB (1024 14-bit words) of Flash program memory rated for 1000 erase/write cycles. It also includes 64 bytes of internal EEPROM data memory for storing calibration values or configuration settings that must persist through power cycles.
What is the maximum operating frequency of the PIC16LF84A-04/SO?
The PIC16LF84A-04/SO suffix '-04' designates a maximum clock frequency of 4 MHz, resulting in an instruction throughput of 1 MIPS. The device supports XT, RC, LP, and HS oscillator modes, giving designers flexibility in selecting the appropriate oscillator type for their frequency and cost requirements.
What supply voltage range does the PIC16LF84A-04/SO support?
The PIC16LF84A-04/SO (LF = low-voltage version) operates from 2.0 V to 5.5 V, covering two AA battery packs (~3 V), CR2032 coin cells (~3 V), 3.3 V regulated supplies, and standard 5 V TTL logic supplies, making it highly versatile for portable and mains-powered applications.
How many I/O pins does the PIC16LF84A-04/SO provide?
The PIC16LF84A-04/SO provides 13 bidirectional I/O pins organized as Port A (5 pins) and Port B (8 pins). Port B features individually configurable internal weak pull-up resistors, and all pins can source or sink sufficient current to directly drive LEDs and small signal loads.
Does the PIC16LF84A-04/SO support in-circuit programming?
Yes. The PIC16LF84A-04/SO supports In-Circuit Serial Programming (ICSP) via two dedicated pins (RB6 and RB7), allowing the device to be programmed and reprogrammed while soldered on the target board using Microchip's PICkit or MPLAB ICD programmers without removing the chip.
