Key Features
- Integrated USB full-speed (12 Mbps) peripheral at 48 MHz enables single-chip USB HID and CDC designs with no external controller
- On-chip DAC and ADC channels support mixed-signal designs requiring both analog generation and measurement in 14 kB Flash
- 14-pin TSSOP package with 12 I/O lines offers the smallest footprint for USB-connected sensor and HID devices
Applications
The PIC16F1455T-I/ST targets USB HID keyboards, game controllers, USB-to-serial bridges, and custom PC interface devices that need a compact 14-pin solution with built-in USB. Its simultaneous ADC and DAC channels allow it to digitize sensor inputs and generate analog control signals within the same 14 kB firmware image, fitting medical wearables and portable instruments. Industrial USB dongles and smart calibration probes also use this device because its TSSOP-14 package reduces PCB area to under 25 mm² while retaining full USB connectivity.

Frequently Asked Questions
How much Flash and RAM does PIC16F1455T-I/ST provide, and can it hold a USB stack?
The PIC16F1455T-I/ST includes 14 kB of Flash program memory and 1024 bytes of SRAM, which is sufficient to store Microchip's USB HID or CDC class library alongside the application state machine and USB descriptor tables without running out of code space.
Does PIC16F1455T-I/ST include both ADC and DAC, and at what resolution?
Yes, the device integrates a multi-channel 10-bit ADC and an on-chip DAC, allowing simultaneous analog input digitization and analog voltage generation within a single 14-pin package at 20 MHz maximum CPU clock, which simplifies mixed-signal designs such as audio equalizers or sensor calibrators.
In what package does PIC16F1455T-I/ST ship and what is the advantage over a 20-pin DIP for a compact USB dongle?
The PIC16F1455T-I/ST comes in a TSSOP-14 package measuring approximately 5 mm x 4.4 mm, roughly one-sixth the board footprint of a 20-pin 300-mil DIP, allowing USB dongle and thumb-drive form factors where the entire controller, USB connector, and decoupling capacitors must fit within 10 mm x 20 mm.
When would PIC16F1455T-I/ST be selected over PIC18F14K50 for a cost-sensitive USB HID design?
PIC16F1455T-I/ST is preferred when the application firmware fits within 14 kB, the design needs only 12 I/O pins, and a smaller TSSOP-14 package with lower per-unit cost is acceptable, whereas PIC18F14K50 with its 16 kB Flash and 20-pin package adds cost and footprint that may be unnecessary for simple USB HID keyboards or USB-to-UART bridges.
