The Microchip PIC32MX695F512L-80I/PF is a 32-bit MIPS M4K microcontroller running at 80 MHz (105 DMIPS) with 512 KB Flash and 128 KB SRAM, housed in a 100-pin TQFP (14x14 mm) package. It integrates USB 2.0 On-The-Go with integrated PHY, a 10/100 Ethernet MAC with MII/RMII, four dedicated DMA channels for USB and Ethernet, a 10-bit 1 Msps ADC, and up to 85 I/O pins, providing a single-chip solution for connected embedded designs. What is a PIC32MX microcontroller? The PIC32MX family is Microchip's general-purpose 32-bit MCU line built on the MIPS M4K core. Within the broader taxonomy, a PIC32MX belongs to: 32-bit microcontroller -> RISC MCU -> embedded processor -> semiconductor IC. The M4K core executes the MIPS32 instruction set with optional MIPS16e code compression (up to 40% smaller code), a 5-stage Harvard pipeline, and a hardware multiplier/divider. This part targets "connectivity" applications (USB + Ethernet + CAN) that previously required external PHY or secondary MCUs. Key features include 512 KB (512K x 8) Flash program memory, 128 KB SRAM, a 16-bit wide instruction path, and peripheral pin select for flexible I/O mapping. The integrated Ethernet MAC supports both MII and RMII interfaces to standard PHYs, while the USB-OTG controller supports device, host, and On-The-Go roles without an external PHY. Eight DMA channels (4 dedicated to USB/Ethernet plus 4 general-purpose) offload data movement from the CPU, sustaining high-throughput streaming at the 80 MHz core clock. Typical applications include industrial Ethernet nodes (Modbus TCP, EtherNet/IP gateways), USB peripherals and embedded hosts (mass storage, HID, CDC), building automation controllers, point-of-sale terminals, and automotive infotainment/telematics prototypes. The combination of USB-OTG and Ethernet on a 100-pin TQFP makes the device attractive for retrofitting older 8/16-bit designs that need to add IP connectivity without moving to a Linux-class SoC. When designing with this part, ensure the 2.5V/3.3V supply rails are properly decoupled (100 nF + bulk) and that the Ethernet PHY reference clock and magnetics meet IEEE 802.3 requirements. Programming is supported by MPLAB X IDE, MPLAB Harmony framework, and the PICkit/Snap/ICD debug probes; the device is pin-compatible across the PIC32MX5xx/6xx/7xx sub-families, simplifying board reuse. This page synthesizes distributor pricing, drop-in PIC32MX alternatives in the same 100-TQFP footprint, and practical design notes that supplement (but do not replace) the manufacturer datasheet DS60001156K.

The Microchip Technology PIC32MX764F128HT-V/MR is a 32-bit MIPS M4K microcontroller operating at 80 MHz with 128 KB of Flash program memory and 32 KB of SRAM, packaged in a 64-pin VQFN (MR, 9x9 mm with exposed pad). It belongs to the PIC32MX5/6/7 family with integrated 10/100 Mbit Ethernet MAC, USB OTG, CAN, and a 10-bit ADC with up to 16 channels, providing industry-leading connectivity and peripheral integration for embedded networking applications. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (SRAM), and integrated peripherals such as timers, communication interfaces, and analog blocks. In the system hierarchy, MCUs sit below microprocessors (MPUs) on integration density: an MCU is a complete compute subsystem on one die, whereas an MPU requires external memory. PIC32 MCUs use the MIPS32 M4K Harvard architecture with a 5-stage pipeline, delivering up to 1.56 DMIPS/MHz and deterministic interrupt response for real-time embedded control. Key features include 80 MHz core speed with 128 KB Flash / 32 KB SRAM, a 10-bit ADC up to 1 Msps with up to 16 input channels, two I2C, two SPI, two UART, USB OTG full-speed, two CAN 2.0b controllers, a 10/100 Ethernet MAC with MII/RMII interface, four 16-bit timers/captures, and a Parallel Master Port (PMP) for external memory or graphics. The device supports up to 53 GPIO pins with 5V tolerant inputs and runs from 2.3V to 3.6V. The PIC32MX764F128HT-V/MR is qualified to industrial temperature range (-40C to +105C ambient, the H suffix) and uses the V (1.6V-2.0V core voltage) performance tier. The 9x9 mm VQFN package with exposed pad provides low thermal resistance (~28 C/W with proper PCB thermal vias) for high-current GPIO driving applications. Typical applications include industrial Ethernet nodes (Modbus TCP, EtherNet/IP), USB device/host peripherals, CAN-based automotive body controllers, HVAC touch interfaces, building automation gateways, and embedded web servers. The integrated Ethernet MAC and USB OTG differentiate this MCU from Cortex-M3 alternatives that require external PHY or USB transceivers, reducing BOM cost and PCB area. When designing with this MCU, allocate the I/O mapping to balance analog and digital functions early, because peripheral pin-select is limited.

Housed in a 64-pin TQFP (10x10 mm) package with the 'V' temperature suffix designating the -40C to +105C industrial range and 'T' denoting tape-and-reel packaging, it ships with 5-variants of the datasheet covering USB, Ethernet, CAN and peripheral-rich options. According to the Microchip product page, the PIC32MX5/6/7 family delivers industry-leading connectivity and peripheral options targeting embedded connectivity-based applications and is fully supported by the MPLAB Harmony integrated software framework. A 32-bit microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash), data memory (SRAM), and a configurable set of on-chip peripherals into one device. The PIC32MX family implements the MIPS32 M4K core architecture - a RISC-style Harvard pipeline that delivers roughly 1.5 DMIPS/MHz, running here at 80 MHz for an effective throughput of ~120 DMIPS. It belongs to the broader taxonomy: MCU -> 32-bit MCU -> PIC32 family -> PIC32MX5/6/7 sub-family -> microcontrollers -> semiconductors. This hierarchy matters for engineers because peripheral selection, memory map and toolchain support are inherited from the family above. Key features include a 10-bit 1 MSPS ADC with up to 16 channels, five 16-bit timers/counters, two I2C, two SPI and two UART interfaces, a Parallel Master Port (PMP) for graphics or external memory, and DMA for offloading CPU data movement. The on-chip USB-OTG controller supports both host and device roles, while the integrated 10/100 Ethernet MAC pairs with an external PHY for networked designs. Hardware CRC, RTCC and a 16-bit parallel capture/comapture/PWM block round out the on-chip peripheral set. Architecturally, the device is built on a low-power CMOS process with multiple power-management modes (Run, Idle, Sleep) and a dedicated low-voltage detect (LVD) block. The Harvard split-bus Flash/SRAM architecture permits simultaneous instruction fetch and data access, and the configurable instruction cache accelerates Flash execution to near zero-wait-state performance. The 64-pin TQFP package exposes a generous pin count for parallel bus, PMP and analog channels while keeping the footprint small enough for cost-sensitive industrial designs. Typical applications include industrial control with Ethernet connectivity, USB-OTG peripherals such as data loggers and instrumentation, CAN-based automotive subsystems, low-cost graphical HMI with PMP-driven LCDs, and connected consumer devices where the PIC32's mature Harmony/PIC32 toolchain and broad peripheral integration reduce BOM and firmware risk. When designing in this part, plan for the external 8 MHz primary oscillator required to drive the 80 MHz system clock via the on-chip PLL, and budget 2.5 mA/MHz active plus 30-50 uA/MHz sleep for power budget calculations. Note that the 'V' suffix extends the operating temperature range to +105C but does not reach automotive -40C to +125C - select an 'I' suffix variant only if lower temperature operation is sufficient.

This device is fully supported by MPLAB Harmony integrated software framework, MPLAB XC32 compiler, and Microchip's full middleware library. Key features of this part include 128 KB Flash and 32 KB RAM, an 80 MHz core with 1.56 DMIPS/MHz throughput, integrated Ethernet MAC with MII/RMII interface, USB On-The-Go with integrated transceiver, two CAN 2.0b modules, and a 16-bit wide parallel master port (PMP) for graphics or external memory. The 100-pin TQFP footprint exposes 5 UARTs, 4 SPI/I2S, 3 I2C, and up to 85 GPIO lines. The PIC32MX764 architecture separates code Flash from data RAM and includes a Prefetch Cache Module that reduces Flash access penalty to one wait state when running at 80 MHz. The peripheral bus matrix gives DMA direct access to RAM, while the USB, Ethernet, and CAN controllers each support independent FIFOs. The 10-bit ADC can scan up to 16 inputs automatically via DMA, offloading repetitive conversions. Typical applications include industrial Ethernet nodes, USB-to-UART bridges, CAN-based automotive body controllers, networked home automation gateways, and embedded web servers using the integrated MAC plus external PHY. The 100-pin package is suited to designs that need both Ethernet and USB plus a large GPIO count. When designing with the PIC32MX764F128L-I/PF, place decoupling capacitors within 5 mm of every VDD/VSS pair, route the 50 MHz Ethernet reference clock with controlled impedance, and provide a clean 3.3 V supply below 50 mV ripple to avoid Ethernet PHY errors.

The Microchip Technology PIC32MX764F128L-V/PF is a 32-bit MIPS32 M4K microcontroller from the PIC32MX5/6/7 family, running at up to 80 MHz with 128 KB of Flash program memory and 32 KB of SRAM, housed in a 100-pin TQFP (14x14 mm) package. It integrates a 10/100 Mbit Ethernet MAC, USB 2.0 Full-Speed On-The-Go, CAN 2.0b, and a 10-bit 1 MSPS ADC with 16 channels. The PIC32MX764F128L-V/PF operates from 2.3 V to 3.6 V and supports an industrial -40C to +105C extended temperature grade (suffix "V"). A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and a rich set of on-chip peripherals used to sense, drive, and connect embedded systems. PIC32MX devices sit in the hierarchy: 32-bit MCU -> MIPS32 M4K core microcontroller -> PIC32 family -> Microchip 32-bit portfolio -> embedded microcontroller -> semiconductor. Compared with 8-bit and 16-bit MCUs, 32-bit PIC32 parts add MPU-class MIPS performance, DMA, and high-bandwidth connectivity (Ethernet, USB-OTG) that older PIC18/PIC24 families cannot deliver. Key features include: 80 MHz MIPS32 M4K core (1.56 DMIPS/MHz, 3.68 CoreMark/MHz), 128 KB Flash with 32 KB RAM, dedicated DMA controller (8 channels), five 16-bit timers, five IC/OC/PWM modules, two UART/I2C/SPI ports plus one USB-OTG and one Ethernet MAC, a 16-channel 10-bit 1 MSPS ADC, and a Parallel Master Port (PMP) for external bus/display expansion. JTAG and 2-wire ICSP debugging are supported. The 100-pin TQFP provides ample GPIO for mixed-signal designs. Architecturally, the PIC32MX7 sub-family adds the integrated Ethernet MAC and USB-OTG PHY interface alongside CAN, making it the most-connected variant of the PIC32MX5/6/7 lineup. The M4K core uses a 5-stage pipeline and hardware multiply/divide; DMA offloads memory-to-peripheral transfers, freeing the CPU for application logic. The 10-bit ADC shares dedicated sampling hardware rather than being software bit-banged. Typical applications: industrial control and HMI panels with Ethernet connectivity, USB device/host peripherals (barcode scanners, data loggers, custom USB audio), CAN-based automotive and building-automation nodes, IoT gateways bridging Ethernet to local sensors, and medical device front panels. Designers often pair the PIC32MX764F128L-V/PF with an external PHY (e.g. DP83848) for Ethernet and with the MCP2200 or MCP2551 for CAN. Design consideration: the VDD/VSS layout for a 100-pin TQFP needs at least four dedicated ground pours and 0.1 uF + 10 uF decoupling per VDD pin pair; failing to do so causes ADC noise and USB enumeration failures. Two analog supply pins (AVDD/AVSS) must be tied to the digital rails through a ferrite bead if ADC accuracy matters.

The device integrates full-speed USB 2.0, CAN 2.0b, 10/100 Ethernet MAC, four DMA channels, and 53 general-purpose I/O pins for embedded connectivity applications. A 32-bit microcontroller (MCU) is an integrated circuit that combines a high-performance processor core, program memory (Flash), data memory (SRAM), and a rich set of on-chip peripherals. PIC32MX5/6/7 devices sit within the broader microcontroller hierarchy: MCU -> 32-bit MCU -> MIPS-based MCU -> PIC32MX family -> industrial/connectivity segment. This taxonomy matters because the PIC32MX764F128LT-I/BG targets the embedded-connectivity sub-tree, combining deterministic real-time control with wired networking stacks that 8-bit and 16-bit MCUs cannot host efficiently. Key features of the PIC32MX764F128LT-I/BG include an 80 MHz core with 1.56 DMIPS/MHz, 128 KB single-cycle-access Flash with prefetch cache to hide flash latency, 32 KB SRAM, four DMA channels for peripheral-to-memory transfers without CPU intervention, and a 16-bit Parallel Master Port (PMP) for external bus expansion. Communication peripherals include USB 2.0 full-speed On-The-Go, CAN 2.0b, 10/100 Mbps Ethernet MAC with MII/RMII interfaces, four UARTs, three SPI/I2S interfaces, and two I2C buses. The industrial -40C to +85C operating range suits factory and outdoor enclosures. The PIC32MX764F128LT uses the MIPS M4K 32-bit RISC core with 5-stage pipeline and hardware multiply/divide. A Flash prefetch module plus 16-bit prefetch cache provide zero-wait-state execution from Flash under most code-flow patterns, helping the 80 MHz core sustain close to its theoretical throughput despite the slow Flash access time typical of embedded Flash processes. The peripheral DMA engine is an architectural advantage: high-bandwidth streams (Ethernet, USB, ADC) move data autonomously, freeing the CPU for protocol and application logic. Typical applications include industrial Ethernet gateways, factory-automation PLCs, building-automation controllers, USB-to-UART bridges, CAN-based motor-control nodes, and embedded web servers. Engineers select this device when the application needs simultaneous Ethernet + CAN + USB connectivity without an external PHY-rich companion IC, plus enough Flash for TCP/IP stacks such as Microchip's MPLAB Harmony Net. When designing with this device, ensure that the TFBGA-121 footprint is layout-friendly - the 0.8 mm ball pitch requires laser-drilled or fine-pitch PCBs and proper microvia stackups. Designers must plan supply decoupling around each VDD/VSS pair as documented in the datasheet, and use the MPLAB X IDE plus Harmony framework for firmware development.

The PIC32MX775F256L uses the MIPS32 M4K core with 5-stage pipeline, hardware multiply/divide, and a single-cycle shadow register set for fast interrupt response. The dual CAN, USB-OTG, and Ethernet MAC make it suitable for connected-embedded applications where the MCU must manage multiple wired protocols concurrently without an external PHY bridge. DMA offloads memory-to-peripheral and peripheral-to-memory transfers, freeing the core for application code. Typical applications include industrial Ethernet gateways, CAN-bridge automotive ECUs, USB Human Interface Devices, embedded web servers, and factory automation controllers. The combination of Ethernet + USB + dual CAN in a single 32-bit MCU reduces BOM and PCB area for connectivity-rich designs. When designing with this part, pay attention to the BGA package - it requires a 4-layer PCB with laser-via fanout for reliable assembly. The MPLAB Harmony framework and XC32 compiler are the canonical toolchain. Decoupling must include 100 nF on every VDD/VSS pair and a bulk 4.7 uF tantalum near the analog supply.

The Microchip Technology PIC32MX775F256L-80I/PF is a 32-bit MIPS M4K microcontroller operating at 80 MHz (105 DMIPS) with 256 KB Flash and 64 KB SRAM, housed in a 100-pin TQFP (14x14 mm) package. It integrates 10/100 Ethernet MAC, USB 2.0 On-The-Go with integrated PHY, two CAN 2.0b controllers, 8 DMA channels, and 83 general-purpose I/O lines, making it one of the most feature-rich members of the PIC32MX5/6/7 family. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as timers, communication interfaces, ADCs, and GPIO into a single chip. The PIC32MX architecture belongs to the broader category of 32-bit embedded microcontrollers (hypernym: MCU -> microcontroller -> embedded processor -> semiconductor) and is designed for connected, real-time, and graphically-rich embedded systems where both deterministic control and high-bandwidth connectivity are required. Key differentiating specifications of this part include 256 KB of self-programmable Flash, 64 KB SRAM, 16-bit parallel master port (PMP) for graphics or external memory, a 10-bit 1 Msps ADC with up to 16 channels, five 16-bit timers/counters, and operation across 2.3V to 3.6V with industrial-grade -40C to +85C temperature range. The 'L' (large pin count) variant offers the maximum 100-pin I/O complement for the family. Architecturally, the PIC32MX775 executes instructions through a 5-stage pipeline with Harvard bus architecture, supporting single-cycle multiplication and hardware divide for high computational throughput. Integrated DMA offloads USB, Ethernet, and CAN transfers from the CPU, freeing cycles for application logic. The USB 2.0 OTG controller embeds the physical transceiver, eliminating external PHY cost and board area. Typical applications include industrial Ethernet gateways, building automation controllers, USB peripherals and HID devices, automotive infotainment and telematics interfaces, CAN-based industrial sensor hubs, and point-of-sale terminals. The combination of Ethernet + USB OTG + dual CAN positions the part uniquely for bridged industrial networks. When designing in this part, ensure the 2.5V/3.3V core supply decoupling is robust - use at least 0.1uF and 10uF ceramic capacitors close to every VDD/AVDD pin. Because the device is supplied in 100-pin TQFP, hand-rework is straightforward, but high-density multilayer routing is recommended to keep analog and digital grounds properly partitioned.

PIC32MX775F256L-80V/BG

PIC32MX775F256L-80V/BG - 32-bit MCU 80MHz 256KB Flash | Microchip

The Microchip PIC32MX775F256L-80V/BG is a 32-bit MIPS M4K microcontroller running at up to 80 MHz (105 DMIPS), integrating 256 KB Flash and 64 KB SRAM with USB-OTG, dual CAN 2.0b, and a 10/100 Ethernet MAC in a 121-ball TFBGA (10x10 mm) package. It operates from 2.3V to 3.6V and is qualified for the -40C to +105C industrial temperature range, supported by the MPLAB Harmony ecosystem. Background: a 32-bit microcontroller (MCU) is a programmable processor-on-a-chip that integrates CPU core, Flash program memory, SRAM, and peripherals (timers, ADC, communication blocks). The PIC32MX family implements the MIPS32 M4K core, a Harvard-architecture RISC with 5-stage pipeline optimized for deterministic interrupt response. Within Microchip's portfolio, PIC32 sits between PIC16/PIC24 (lower pin counts, simpler peripherals) and the Cortex-M class (often faster cores, similar peripheral richness). It is best understood as: MCU -> 32-bit MCU -> MIPS MCU -> PIC32MX family -> connectivity class (Ethernet + USB-OTG + CAN). Key features: 8-channel DMA, 16-bit parallel master port, 5 16-bit timers/capture/compare, two I2C, two SPI, four UART, USB-OTF 2.0 peripheral with integrated PHY, dual CAN 2.0b modules with 1024 message buffers, and a 10/100 Ethernet MAC with MII/RMII interfaces. The IC ships in 121-ball TFBGA (10x10 mm) and provides up to 83 I/O pins for mixed-signal or connectivity-heavy designs. Technical depth: the M4K pipeline plus 8 dedicated DMA channels offload USB-OTG, Ethernet, and CAN traffic from the CPU, enabling deterministic throughput on the simultaneous-communication scenarios this part is designed for. The 16-bit PMP plus DMA simplifies connection to graphic controllers, external bus memories, or FPGA co-processors. Typical applications: industrial Ethernet gateways, CAN/J1939 nodes, USB-OTG device/host controllers, embedded web servers, and motor-control HMIs. Design tip: ensure the BGA substrate via-in-pad microvia stack matches the 0.65 mm ball pitch; JTAG/Trace must be brought out for MPLAB ICD 3 / REAL ICE in-circuit debug.

PIC32MX775F256L-80V/PF - 80MHz 32-bit MCU w/ 256KB Flash | Microchip

The Microchip Technology PIC32MX775F256L-80V/PF is a 32-bit MIPS32 M4K microcontroller running at up to 80 MHz with 256 KB of Flash program memory and 64 KB of SRAM, housed in a 100-pin TQFP (14x14 mm) package. It integrates a 10/100 Mbit Ethernet MAC, USB-OTG, two CAN modules, and a 10-bit ADC, making it a connectivity-rich MCU for embedded networking applications. A 32-bit microcontroller (MCU) is a single-chip computer built around a 32-bit data path and instruction set, offering higher throughput, larger addressable memory, and richer peripherals than 8-bit or 16-bit MCUs. The PIC32MX family sits in the hierarchy: 32-bit MCU -> MIPS-based MCU -> PIC32 family -> PIC32MX5/6/7 sub-family, which Microchip positions as the entry-level 32-bit platform with on-chip connectivity peripherals. Key features of the PIC32MX775F256L-80V/PF include: 256 KB Flash organized as 256K x 8, 64 KB SRAM, a 10-bit ADC with up to 16 channels and 1 Msps conversion rate, 5 general-purpose 16-bit timers/counters, an RTCC, and a DMA controller with 4 channels. The device operates from 2.3V to 3.6V and supports an industrial temperature range of -40C to +105C, making it suitable for harsh environments. Communication peripherals include USB-OTG, two CAN 2.0B controllers, 10/100 Ethernet MAC with MII/RMII interface, four UARTs, three SPI ports, and two I2C ports. Architecturally, the PIC32MX uses the MIPS32 M4K core, a 5-stage pipeline RISC architecture with single-cycle multiply and hardware divide. The 80 MHz clock delivers 1.56 DMIPS/MHz (Dhrystone 2.1) of integer performance. The integrated DMA controller offloads data movement between peripherals and memory, freeing the CPU for application logic. Code is fully supported by MPLAB X IDE, MPLAB Harmony v3 framework, and the XC32 compiler. Typical applications include industrial Ethernet nodes (Modbus TCP, EtherNet/IP gateways), CAN-based automotive body and powertrain networks, USB-OTG device/host peripherals, building automation controllers, and embedded web servers. The wide peripheral integration makes the device particularly suited for connected sensor hubs and IoT edge nodes requiring multiple wired interfaces. A key design consideration is that this MCU does not include an integrated PHY - Ethernet applications require an external PHY such as the LAN8720A or DP83848. Decoupling: place 0.1 uF ceramic capacitors on each VDD pin and a bulk 10 uF tantalum or ceramic near the voltage regulator; the device is sensitive to supply noise during ADC conversions. This page synthesizes verified distributor pricing, drop-in alternative MPNs in the same 100-pin TQFP footprint, and practical design notes not collected in any single datasheet page, helping procurement and firmware engineers shorten BOM selection cycles.
