PIC32MX370F512L-I/TL 개요
A microcontroller (MCU) is a single-chip computer that combines a CPU core, program memory (Flash), data memory (SRAM), and a rich set of on-chip peripherals. The PIC32MX3/4 family sits in Microchip's MIPS-based 32-bit MCU portfolio, between 8-bit PIC16/PIC18 MCUs and higher-end Cortex-M parts, balancing cost with deterministic 32-bit performance for embedded applications requiring USB, graphics, or audio interfaces.
Key features of the PIC32MX370F512L-I/TL include a 120 MHz/150 DMIPS ceiling on the family (this -I/TL grade runs to 80 MHz), 512 KB Flash, 128 KB SRAM, 4 KB EEPROM emulation area, hardware Multiply/Divide and prefetch cache for deterministic 80 MHz throughput, USB 2.0 full-speed device/host/OTG, two SPI/I2S ports, two I2C ports, five UART modules, a 10-bit ADC with 28 input channels (500 ksps), and a parallel master port supporting 8-bit or 16-bit external bus for graphics or external memory.
The MIPS32 M4K core executes most instructions in one clock cycle, and on-chip dual-port SRAM allows simultaneous DMA and CPU access without contention. The 124-pin VTLA (VTLA = Very Thin Leadless Array) package with exposed thermal pad delivers a small 9x9 mm footprint suitable for space-constrained designs, while still exposing 84 GPIO and the parallel master port for external memory or LCD interfaces.
Typical applications for the PIC32MX370F512L-I/TL include USB peripherals (HID, CDC, MSD, audio class), graphics HMI displays, audio processing with I2S codecs, industrial control panels, point-of-sale terminals, sensor aggregators, and low-cost 32-bit upgrades for legacy PIC24 designs. The 80 MHz ceiling keeps power consumption reasonable for battery-powered USB peripherals.
When designing with this part, allocate enough decoupling (0.1 uF + 10 uF near each VDD/VBUS pin), reserve PGECx/PGEDx for ICSP, and check the family errata before locking the BOM. The VTLA package requires careful PCB layout - the exposed pad must be soldered to a sufficient copper area for thermal dissipation and electrical grounding.

일반적인 애플리케이션
PIC32MX370F512L-I/TL 적합 용도: 6 애플리케이션s: USB Human Interface Devices (HID / CDC / MSD), Graphics HMI with Parallel Master Port, Audio Processing with I2S Codecs, Industrial Control Panels, Point-of-Sale Terminals and Printers, Sensor Aggregation Hubs.
USB Human Interface Devices (HID / CDC / MSD)
The PIC32MX370F512L-I/TL is purpose-built for USB peripherals. Its integrated USB 2.0 full-speed PHY supports device, host, and OTG modes without external components, and the 512 KB Flash easily holds Microchip's free USB stack (USB Device/Host/OTG) plus class drivers. The 80 MHz MIPS32 M4K core delivers deterministic 1-cycle execution for HID polling, and the 128 KB SRAM provides headroom for CDC serial buffers and MSD SCSI emulation.
추천
Graphics HMI with Parallel Master Port
The PIC32MX370F512L-I/TL drives graphical LCDs through its parallel master port (PMP), which supports 8-bit or 16-bit external data bus plus dedicated control lines. With 128 KB SRAM and 84 GPIO, the part can frame-buffer small QVGA/WQVGA panels and run Microchip's graphics library (MLA) without external memory. The 80 MHz core sustains typical 30 FPS drawing rates on QVGA panels.
추천
Audio Processing with I2S Codecs
The two on-chip I2S ports interface directly to audio DACs and ADCs, enabling 16-32-bit stereo audio at 8-48 kHz sample rates. Combined with 128 KB SRAM, the PIC32MX370F512L-I/TL can buffer audio frames for effects processing, USB audio class streaming, or local MP3-style decoding. The 80 MHz MIPS32 core executes audio DSP routines with predictable latency and no OS overhead.
추천
Industrial Control Panels
The PIC32MX370F512L-I/TL's 28-channel 10-bit ADC, two analog comparators, 84 GPIO, and industrial -40 to +85 C temperature range suit it to PLC-style I/O expansion modules, motor-control signal conditioning front-ends, and sensor-aggregation hubs. The 512 KB Flash is enough for protocol stacks (Modbus, CANopen via SPI external controller), and the parallel master port allows external SRAM expansion for data logging.
추천
Point-of-Sale Terminals and Printers
POS terminals need USB device (to host), LCD graphics, keypad scanning, and thermal-printer stepper driving - all of which the PIC32MX370F512L-I/TL addresses in one chip. The integrated USB 2.0 device, parallel master port for graphics, 84 GPIO for keypad/printer drivers, and 512 KB Flash for embedded application firmware eliminate external logic and shorten BOM.
추천
Sensor Aggregation Hubs
The 5 UART, 2 I2C, and 2 SPI/I2S channels let the PIC32MX370F512L-I/TL aggregate data from many peripheral sensors, log to external SPI flash, and forward over USB or UART. The 28 ADC channels enable direct analog sensor sampling at 500 ksps, while 128 KB SRAM buffers raw data before post-processing.

설계 노트
The PIC32MX370F512L-I/TL requires 2.5 V or 3.3 V supply. Place a 10 uF bulk capacitor and a 0.1 uF ceramic capacitor on each VDD/VSS pair, physically close to the IC. The USB VBUS pin (when used in host mode) draws up to 500 mA and must be current-limited per USB 2.0 spec.
Estimated: at 80 MHz full-load, the VTLA-124 (9x9 mm) package dissipates under 200 mW; the exposed thermal pad MUST be soldered to a copper pour of at least 1 square inch for ground and thermal dissipation. Without the exposed pad, junction temperature can rise sharply in enclosed housings.
The VTLA package is leadless - PCB land pattern must exactly match Microchip's package drawing. Reserve PGECx/PGEDx pins for ICSP programming/debugging and route them with short traces to a 6-pin header. Keep analog AVSS/AVDD traces separate from digital VDD/VSS to minimize ADC noise injection.
Check the PIC32MX3/4 family errata sheet (DS80000490) before locking the BOM - certain silicon revisions have USB suspend behavior and PMP timing constraints that require software workarounds. Also note that the -I/TL speed grade is 80 MHz; using firmware with the PLL configured for 120 MHz will exceed the rated speed and cause unreliable operation.
