PIC32MX795F512L-80I/TL 개요
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a processor core, program memory, working RAM, and a wide range of peripherals on one die. PIC32MX MCUs sit in the broader taxonomy of microcontroller -> embedded controller -> system-on-chip -> semiconductor. Compared with 8-bit or 16-bit MCUs, 32-bit devices deliver substantially more compute per MHz, larger linear address spaces, and richer connectivity peripherals, which makes them suitable for networked and graphical products that previously required an external processor.
Key features include a 16-channel 10-bit ADC, five 16-bit timers, an internal 8 MHz and 32 kHz oscillator pair, an integrated Real-Time Clock Calendar (RTCC), and a Charge Time Measurement Unit (CTMU). The 80 MHz core, 1.56 DMIPS/MHz pipeline and hardware Multiply/Divide yield 124 DMIPS, allowing deterministic handling of Ethernet stacks, USB stacks, and CAN applications concurrently. 512 KB self-programmable Flash with EEPROM emulation supports in-field firmware upgrades.
Typical applications include industrial Ethernet nodes, CAN-based automotive body and motor-control gateways, USB device and embedded-host products, and connected appliances. The combination of Ethernet plus CAN and USB in a single device eliminates external bridge ICs, reducing PCB area and BOM cost.
Designers should observe the maximum 80 MHz system clock across the -40C to +85C industrial temperature range and provide adequate decoupling. JTAG and two-wire ICSP interfaces are supported for MPLAB X IDE development with MPLAB Harmony and XC32 toolchains.

일반적인 애플리케이션
PIC32MX795F512L-80I/TL 적합 용도: 6 애플리케이션s: Industrial Ethernet Gateway / PLC Node, CAN-Based Automotive Body Controller, USB Device and Embedded Host Product, Connected Graphical HMI / Touch Display, Secure Connected Appliance with RTCC and Crypto, Audio / Connectivity Bridge for Embedded Designs.
Industrial Ethernet Gateway / PLC Node
The PIC32MX795F512L-80I/TL is purpose-built for industrial Ethernet nodes thanks to its integrated 10/100 Mbit MAC and 80 MHz MIPS32 M4K core, which can sustain TCP/IP stacks plus a real-time application layer. Engineers typically pair this MCU with an external PHY (such as a Microchip KSZ8061 or DP83848) on the MII/RMII interface, then run lwIP or Microchip's own TCP/IP stack alongside EtherNet/IP or Modbus TCP. The 128 KB SRAM is large enough to hold multiple sockets concurrently. With 85 GPIOs the device directly drives opto-isolated inputs and relays without external I/O expanders, simplifying BOM and reducing cost for PLC and IO-Link gateway designs.

CAN-Based Automotive Body Controller
The dual CAN 2.0b controllers combined with 512 KB Flash and 128 KB SRAM make the PIC32MX795F512L-80I/TL a fit for automotive body and chassis ECUs that aggregate multiple CAN buses (for example, body CAN and powertrain CAN) at the same time. The 16-channel 10-bit ADC reads sensor inputs at up to 500 ksps, while five 16-bit timers generate PWM outputs for lighting or motor drive. Designers pair the device with CAN transceivers such as MCP2551 or TJA1050. The industrial temperature grade covers cabin environments, but -V parts should be considered for under-hood positions. Note: this is industrial grade; AEC-Q100 automotive qualification is not claimed.

USB Device and Embedded Host Product
With USB 2.0 On-The-Go supporting Host, Device, and OTG modes, the PIC32MX795F512L-80I/TL can serve as either a USB device (vendor-specific function, CDC, HID, MSD, or audio class) or an embedded USB host that manages mass storage, HID peripherals, or printers. The 80 MHz core sustains the USB stack with adequate headroom for application logic, while the 16-channel ADC and 85 GPIOs interface directly to user controls. Typical examples include data loggers that mount as MSD to PCs, label printers, and USB host adapters for legacy industrial equipment. The integrated USB transceiver eliminates the need for an external ULPI chip, cutting BOM cost.

Connected Graphical HMI / Touch Display
The 124 GPIO count, 80 MHz performance, and 128 KB SRAM allow the PIC32MX795F512L-80I/TL to drive small graphical TFT displays via PMP or SPI interfaces while concurrently serving a web interface through the integrated Ethernet MAC. Typical use cases include HVAC controllers, building-automation touch panels, and medical-device operator interfaces. The CTMU and RTCC simplify capacitive touch-button scanning and time-stamped event logging without external real-time-clock chips. Designers often pair this MCU with a small TFT driver and resistive or projected-capacitive touch controller, providing a cost-effective 32-bit HMI solution with full connectivity.

Secure Connected Appliance with RTCC and Crypto
The integrated Real-Time Clock Calendar (RTCC) and 512 KB Flash make the PIC32MX795F512L-80I/TL a strong fit for connected appliances that need to keep accurate time across power cycles (white goods, smart thermostats, vending machines). The 128 KB SRAM supports SSL/TLS session buffers for HTTPS, MQTT, or TLS-secured cloud connections. The 32-bit MIPS32 M4K core executes AES or ChaCha20 software crypto at usable rates for small messages. The 80 MHz core plus the integrated Ethernet MAC deliver a single-chip solution that removes the need for an external network processor, lowering BOM cost by USD 2-3.
추천
Audio / Connectivity Bridge for Embedded Designs
The PIC32MX795F512L-80I/TL provides a robust platform for audio-over-network bridges (such as Dante-compatible prototypes or simple streaming audio applications) because it combines Ethernet bandwidth with 5 I2C and 4 SPI interfaces to drive external audio CODECs and DSPs. The I2S or AC97 interface is not native to this part, so external I2S transceivers are needed for full audio paths. Designers use the DMA engine and 5 timers for sample-rate timing. Combined with the USB host, the device can also act as a USB-to-SPDIF bridge, making it useful for legacy audio DAC and amplifier designs.

설계 노트
The PIC32MX795F512L-80I/TL operates from a 2.3V to 3.6V supply; designers typically use an LDO such as MCP1700 or MIC29150 to derive the 3.3V rail from a 5V upstream source. Place at least one 10 uF bulk cap plus a 0.1 uF ceramic decoupling cap adjacent to each power pin pair. The internal 8 MHz RC plus PLL drives 80 MHz, but USB requires the 48 MHz USB clock branch, so the 48 MHz PLL output must be within +/- 0.25% to meet USB 2.0 timing. Add a ferrite bead if the analog 3.3V rail shares a converter with the digital 3.3V rail.
Route the USB DP/DM signals as a 90 ohm differential pair with no stubs and matched length within 50 mil. The MII/RMII Ethernet signals should also be routed as 50 ohm controlled-impedance traces; for RMII, keep traces under 25 mm if possible. The 124-VTLA package has a center thermal pad that should be soldered to a 1 sq. in. copper pour for best thermal performance. Provide a separate analog ground island under the ADC pins and stitch it to digital ground only at the MCU's AGND pin to keep ADC noise below 1 LSB.
Do not assume that PIC32MX family parts are code-compatible across all sub-families: the MX570 and MX575 sub-families lack the Ethernet MAC, while the MX675/MX695/MX795 families add CAN. Verify the part number suffix carefully: -80I/TL = 80 MHz, industrial temp, VTLA-124 package; -80V/TL = 80 MHz, extended temp, VTLA-124; -80I/PF = 80 MHz, industrial, TQFP-100. Mixing the package suffixes is the most common BOM-line mistake. Also confirm the JTAG TCK/TMS/TDI/TDO pins are not repurposed as GPIO at reset, or JTAG debug will silently fail.
Estimated: at 80 MHz with all peripherals active and all GPIO toggling, the PIC32MX795F512L-80I/TL typically draws 70-95 mA at 3.3V, yielding roughly 0.25-0.32 W dissipation. With the 124-VTLA package thermal resistance (theta_JA) around 30 C/W on a 4-layer PCB with 1 sq. in. copper, junction temperature rise is approximately 7.5-9.5 C above ambient. This keeps Tj well within the 125 C maximum at 85 C ambient, but designers in enclosed enclosures at high ambient should verify with a thermal camera in the final housing.
