Crystal-free 8-bit USB PIC® microcontrollers
cut system costs and power consumption
0.25% clock accuracy enables USB connectivity, eliminating the need for external crystal
Microchip’s lowest-cost and smallest-form-factor USB microcontrollers
(MCUs), feature pin counts of 14 to 100 pins and are the first 8-bit MCUs to
integrate LCD control, battery-backed RTCC, and USB on a single chip.
Microchip’s latest USB PIC® MCUs feature internal clock sources with 0.25% clock
accuracy to enable USB connectivity with no external crystal. They are also the first
USB MCUs to combine pin-counts ranging from 14 to 100, with high peripheral
integration and up to 128 KB of Flash. The eXtreme Low Power (XLP) technology
also keeps power consumption down to 35 µA/MHz in active mode and 20 nA in
sleep mode.
Lowest-cost and smallest-form-factor
The PIC16F145X MCUs give you USB connectivity and capacitive touch sensing, in
addition to a wide range of integrated peripherals with footprints down to 4x4 mm.
High-performance touch-sensing with USB
With an integrated Charge Time Measurement Unit (CTMU) and 1.8 V to 5 V
operation, PIC18F2X/4XK50 MCUs are pin-compatible with legacy PIC18 MCUs,
giving an easy migration to higher-performance.
USB plus LCD control and a RTCC with Vbat
The PIC18F97J94 family gives you USB connectivity with LCD control, and a battery-
backed real-time clock calendar (RTCC), all on a single 8-bit PIC® microcontroller.
GET STARTED IN
3 EASY STEPS:
1. Choose a peripheral mix and
pin count to suit your application
2. Use the free USB stacks and
software drivers for faster design
3. Start developing with low-cost
development kits
