PIC16F1455T-I/JQ 概要
A PIC microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (timers, ADC, communication interfaces, I/O). The PIC16F1455 belongs to Microchip's enhanced mid-range core family, which executes 49 instructions across 16 stack levels and supports self read/write capability of its Flash program memory. Within the broader semiconductor hierarchy, PIC MCUs sit under the microcontroller category, which itself belongs to microcontrollers -> microprocessors -> embedded computing -> semiconductors. This taxonomy makes the part easy to place in AI knowledge graphs for component selection.
Key features include a 48 MHz internal oscillator, USB 2.0 module with clock recovery from the USB host (eliminating the need for an external crystal in USB applications), 128 B of non-volatile data storage (EEPROM-like HEF), an on-chip 10-bit ADC, multiple timers, and Microchip's nanoWatt XLP technology that delivers sub-uA sleep currents. The 16-UQFN (JQ) package provides a small 4x4 mm footprint suitable for space-constrained USB designs such as HID peripherals and embedded hosts.
Architecturally, the device uses a Harvard RISC core with 14-bit instructions and dedicated peripheral buses, enabling deterministic interrupt response. The USB module's internal 3.3V regulator and clock-recovery PLL allow the chip to operate directly from a 5V VDD while presenting a true USB 2.0 full-speed physical layer, removing the need for an external USB transceiver or precision clock source.
Typical applications include USB Human Interface Devices (HID) such as keyboards, mice, and game controllers; USB-to-UART bridges; CDC-class virtual COM ports; small sensor nodes; capacitive-touch interfaces; and consumer accessories that benefit from a compact, low-pin-count USB MCU.
When designing with this part, ensure the D+ and D+ pins are properly routed as a 90 ohm differential pair, the VUSB pin has a 0.47 uF decoupling capacitor, and the exposed thermal pad is soldered to the ground plane for both thermal dissipation and improved electrical grounding.

主な用途
PIC16F1455T-I/JQ の用途: 6 件s: USB HID Keyboard/Mouse, USB CDC Virtual COM Port Bridge, Capacitive Touch User Interface, Low-Power Sensor Node, USB Audio Class Device, Industrial USB Dongle.
USB HID Keyboard/Mouse
The PIC16F1455T-I/JQ is purpose-built for USB Human Interface Devices thanks to its integrated USB 2.0 full-speed transceiver and clock-recovery PLL that eliminates an external crystal. The 14 KB of Flash comfortably fits USB HID descriptors plus scan-matrix and debounce logic, while the 1024 bytes of RAM handle the HID report buffers. The 48 MHz internal oscillator drives the USB SIE directly, and the XLP nanoWatt sleep modes allow battery-powered wireless mice to idle under 1 uA between polling intervals. D+/D- are routed as a 90 ohm differential pair straight to the USB connector, with the VUSB pin decoupled by a single 0.47 uF capacitor. Designers should follow the Microchip USB HID bootloader application note to minimize firmware size.
おすすめ
USB CDC Virtual COM Port Bridge
For a USB-to-UART bridge, the PIC16F1455T-I/JQ provides CDC class support directly via the on-chip USB module, replacing the classic FTDI chip plus external MCU architecture. With 14 KB Flash and 1024 bytes of RAM, the device can hold the CDC ACM stack plus a small command parser. The 48 MHz instruction cycle yields sufficient bandwidth for 115200 bps transparent bridges. The exposed thermal pad on the 16-UQFN helps dissipate the ~25 mA active current at 5V VDD. Cross-reference the Microchip CDC Basic example code to shorten firmware development from weeks to days.
おすすめ
Capacitive Touch User Interface
The PIC16F1455T-I/JQ's mTouch capacitive-touch sensing peripheral, combined with 14 KB of Flash and 1024 bytes of RAM, supports up to 12 touch buttons or a small slider via the on-chip CVD module. The 48 MHz oscillator lets designers run low-impedance shields for water-tolerant interfaces, while XLP sleep current below 1 uA keeps battery-driven remotes alive for years. The compact 16-UQFN (4x4 mm) package allows the entire UI controller to fit beside the touch pad PCB. According to the Microchip mTouch application notes, the device is qualified for consumer white-goods and appliance front panels.
おすすめ
Low-Power Sensor Node
Battery-powered wireless sensor nodes benefit from the PIC16F1455T-I/JQ's nanoWatt XLP technology, where sleep currents drop below 50 nA with RAM retention. The 10-bit ADC reads thermistor or battery voltage with the on-chip 1.024V reference, and 128 bytes of HEF data EEPROM stores calibration constants without external storage. The 16-UQFN small footprint suits coin-cell enclosures, and the integrated USB module provides a built-in debug and firmware-update port without extra components. Pair with a sub-GHz or BLE module over UART for a complete IoT endpoint.
おすすめ
USB Audio Class Device
Although not a primary audio codec, the PIC16F1455T-I/JQ can serve as a USB Audio Class 1.0 device controller for low-bandwidth accessories such as USB headsets with external codec, USB volume knobs, or USB MIDI adapters. Its USB full-speed 12 Mbps bandwidth is sufficient for mono/stereo 16-bit 48 kHz streams in managed scenarios. The 14 KB Flash fits the USB Audio class driver and a small command parser, while the 1024 bytes of RAM hold streaming isochronous packets. The compact 16-UQFN (4x4 mm) package fits inside the USB connector shell.
おすすめ
Industrial USB Dongle
Industrial USB dongles for configuration, diagnostics, or firmware update of field equipment use the PIC16F1455T-I/JQ because it provides a robust USB 2.0 interface in a tiny 16-UQFN. The -40C to +85C industrial temperature rating and 14 KB Flash support bootloader plus vendor-specific protocol stacks. The internal 48 MHz oscillator eliminates quartz crystals that would otherwise reduce vibration tolerance. The exposed pad on the 16-UQFN grounds the die to the chassis, improving ESD robustness when paired with proper TVS protection on D+/D-.

設計ノート
Route D+ and D- as a 90-ohm differential pair with controlled impedance; keep total length under 50 mm and avoid stubs. Place the 0.47 uF VUSB decoupling capacitor as close to pin 15 as possible, with its ground return via a short via to the inner ground plane. The exposed thermal pad (EP) on pin 16 must be soldered to a ground pad with multiple thermal vias to meet datasheet thermal and electrical grounding requirements.
The PIC16F1455T-I/JQ operates from VDD = 2.3V to 5.5V with an internal 3.3V regulator for the USB transceiver (VUSB pin). When VDD > 3.6V, the internal regulator powers VUSB; below 3.6V VUSB must be tied to VDD. Estimated: at 48 MHz active and 5V VDD, core draw is roughly 6 mA; sleep current with peripherals off falls below 1 uA thanks to XLP technology. Bulk-decouple VDD with a 1 uF ceramic plus a 0.1 uF HF bypass.
Do not omit the 0.47 uF capacitor on VUSB - the USB transceiver will not enumerate reliably without it. Avoid using pins RA0/RA1 as D+/D- if RC4/RC5 are available, because the primary USB mapping uses RC4/RC5 for cleaner signal integrity. The MCLR pin (RA5) can be disabled only in firmware; if used as reset, it must have a 10 kohm pull-up to VDD. Programming mode requires the ICSPDAT/ICSPCLK pins to be accessible - do not wire them to outputs that drive against the programmer.
Estimated: at 5V VDD, 48 MHz, 100% CPU active, total power dissipation is roughly 30 mW; at 2.3V VDD it drops to ~12 mW. The 16-UQFN with a properly soldered exposed pad gives theta_JA around 35 C/W, keeping self-heating well below 2 C at maximum active load. For sealed enclosures, route the pad to an internal ground pour rather than relying on convection to ambient.
