Product details
Overview
TDGL022 from Microchip Technology is a 32-bit Flash microcontroller based on the MIPS32® M4K® core, operating at up to 80 MHz with 128 KB program memory (plus 12 KB boot Flash), 32 KB SRAM, and integrated USB 2.0 full-speed OTG controller. It features a 10-bit 16-channel ADC (1000 ksps), five 16-bit timers, two UARTs, two I²C modules, two SPI modules, and hardware DMA support - deployed in industrial control, USB peripheral interfaces, and embedded data acquisition systems.
For engineers reviewing the TDGL022 datasheet, TDGL022 pinout, TDGL022 application, or TDGL022 equivalent, this page delivers verified electrical specs, package mapping, functional pin roles, real-world use cases, and validated alternative options for design-in and supply continuity planning.
Technical Context
The TDGL022 implements a 5-stage pipeline MIPS32 M4K CPU with MIPS16e® code compression, prefetch cache, and dual PLLs - one dedicated to USB clock generation (48 MHz) and another for CPU operation. It supports atomic SET/CLEAR/INVERT operations on peripheral registers and includes fail-safe clock monitoring with configurable watchdog timer.
Its USB subsystem integrates a dedicated DMA channel, on-chip transceivers (D+/D−), VBUS sensing (VBUSON), and USBID detection - enabling host, device, and OTG roles without external PHY. Analog subsystem includes CVREF voltage reference, dual comparators, and simultaneous ADC conversion during Sleep/Idle modes.

Pinout & Package
TDGL022 is packaged in a 64-pin QFN (MR) with exposed thermal pad (not electrically connected; recommended to tie to VSS). Pin count, layout, and signal assignment match PIC32MX440F128H per Microchip DS61143H, including USB-specific pins D+/RG2, D−/RG3, VBUS, VUSB, and USBID/RF3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D+/RG2 | USB differential data positive | Direct connection to USB connector; requires 36 Ω series termination per USB spec |
| D−/RG3 | USB differential data negative | Paired with D+; forms full-speed differential pair routed as controlled-impedance trace |
| VBUS | USB bus voltage sense input | Monitors host-supplied 5V; enables automatic device/host role negotiation in OTG mode |
| VUSB | USB transceiver power supply | Must be decoupled with 1 µF ceramic; powers internal USB PHY circuitry |
| USBID/RF3 | USB ID pin for OTG role detection | Pulled low via resistor to identify peripheral mode; floating or pulled high for host mode |
| VCAP/VCORE | Core voltage decoupling terminal | Requires 10 µF tantalum + 0.1 µF ceramic capacitor close to pin for stable 1.8V core regulation |
Key Features
| Feature | Design Value |
|---|---|
| USB OTG with dedicated DMA | Enables zero-CPU-overhead data transfers between USB endpoints and memory buffers |
| Hardware Real-Time Clock & Calendar (RTCC) | Retains time/date across sleep modes using external 32.768 kHz crystal or internal RC oscillator |
| Atomic peripheral register access | Eliminates read-modify-write race conditions for interrupt-safe GPIO and PWM control |
| Configurable open-drain I/O | Allows direct wire-OR logic (e.g., I²C bus pull-up) without external components |
| Fail-Safe Clock Monitor (FSCM) | Switches to backup oscillator and triggers interrupt if primary oscillator fails - critical for safety-critical firmware |
| High-current I/O (18 mA sink/source) | Drives LEDs, small relays, or optocouplers directly without buffer transistors |
Applications
| Industrial USB Data Logger | USB Human Interface Device (HID) |
|---|---|
|
Use Scenario: Standalone environmental monitor collecting temperature, humidity, and pressure data via analog sensors and storing timestamps locally before bulk upload over USB. IC Role / Device Role: Central controller managing ADC sampling, RTCC timestamping, Flash logging, and USB mass-storage-class enumeration. Use Value: Integrated USB OTG and 32 KB SRAM enable seamless file-based data transfer without external USB bridge IC or RAM expansion. |

Use Scenario: Protocol translator converting RS-485 Modbus RTU traffic to USB CDC ACM virtual COM port for PC-based SCADA software. IC Role / Device Role: Dual-role bridge: UART1 handles RS-485 with hardware flow control; USB handles CDC ACM class enumeration and data tunneling. Use Value: Two UARTs with IrDA encoder/decoder and RS-485 support eliminate need for level-shifting transceivers in many configurations. |
Use Scenario: Wireless sensor node with local processing, where firmware updates are delivered via USB instead of OTA, minimizing RF exposure and power consumption. IC Role / Device Role: Secure bootloader host: validates signed firmware images in Flash, manages dual-bank update, and exposes DFU interface over USB. Use Value: 128 KB Flash + 12 KB boot Flash provides space for robust secure bootloader and application partitioning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-enabled microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIC32MX440F128H | Identical core, memory, USB, and peripheral set; differs only in marking and packaging (64-pin TQFP vs. QFN) | Same USB OTG functionality and pin-compatible I/O mapping; TQFP offers easier prototyping and rework | Select when board layout allows larger footprint or hand-soldering is required |
| STM32F103CBT6 | ARM Cortex-M3 core, 128 KB Flash, 20 KB SRAM, USB 2.0 full-speed - no dedicated USB DMA or CVREF | Lacks hardware RTCC, analog comparator CVREF, and atomic peripheral access; requires external RTC or precision reference | Choose for ARM ecosystem alignment, but expect additional external components for equivalent analog/USB timing capability |
Compared with PIC32MX440F128H, TDGL022 offers identical functionality in a thermally enhanced QFN package ideal for space-constrained industrial modules; versus STM32F103CBT6, TDGL022 delivers superior analog integration, USB DMA efficiency, and deterministic real-time behavior without external support components.
