Product details
Overview
CY8C3MFIDOCK-128 from Infineon Technologies is a PSoC 3 programmable system-on-chip MCU featuring an 8051 CPU core, 128 KB flash, 8 KB SRAM, and integrated CapSense® capacitive sensing capability in a 68-pin QFN package. It supports mixed-signal programmability with configurable analog and digital blocks for embedded control applications including human interface devices and industrial sensors.
For engineers reviewing the CY8C3MFIDOCK-128 datasheet, CY8C3MFIDOCK-128 pinout, CY8C3MFIDOCK-128 application, or CY8C3MFIDOCK-128 equivalent, key selection criteria include CapSense® channel count, flash endurance (100K write/erase cycles), operating voltage range (1.71–5.5 V), and USB 2.0 full-speed interface support.
Technical Context
The CY8C3MFIDOCK-128 implements a single-cycle 8051 CPU running up to 67 MHz, paired with a programmable analog subsystem including up to 20-bit Delta-Sigma ADCs and rail-to-rail op-amps. Its digital routing matrix enables dynamic reconfiguration of UDBs (Universal Digital Blocks) for custom logic and state machines.
CapSense® subsystem supports up to 64 self- or mutual-capacitance buttons/sliders with hardware-accelerated baseline tracking and noise immunity algorithms. USB functionality includes integrated transceiver, PHY, and endpoint buffers compliant with USB 2.0 full-speed specification.
Key Specifications

|---|---|
| CPU Core | Single-cycle 8051, 67 MHz max - enables deterministic real-time control with low interrupt latency |
| Flash Memory | 128 KB, 100K write/erase cycles - supports field firmware updates and robust code storage |
| SRAM | 8 KB - sufficient for stack, heap, and real-time data buffering in sensor fusion tasks |
| CapSense® Channels | Up to 64 - allows complex touch interfaces (e.g., multi-zone sliders, proximity wake-up) |
| USB Interface | Full-speed (12 Mbps), integrated PHY - eliminates external transceiver, reduces BOM cost and layout area |

| I/O Count | 58 programmable GPIOs - includes configurable slew rate, drive strength, and internal pull-ups/downs |
Pinout & Package
68-pin QFN (10 mm × 10 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad. RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA/VDDD | Analog/Digital Power Supply | Separate 1.71–5.5 V supplies enable noise isolation between analog sensing and digital logic |
| IOx[0:57] | Programmable GPIO | Each supports CapSense®, UART, SPI, I²C, PWM, and interrupt-on-change with hysteresis |
| USB_DP/USB_DM | USB Differential Pair | Integrated full-speed transceiver with on-chip termination - no external resistors required |
| XTAL_IN/XTAL_OUT | Crystal Oscillator Input/Output | Supports 1–33 MHz crystals for precise timing; internal PLL enables 67 MHz CPU clock |

| Programmable Analog Subsystem | Configurable op-amps, comparators, and 20-bit Delta-Sigma ADCs enable sensor signal conditioning without external components |
| UDB-Based Digital Logic | Reconfigurable logic fabric supports custom counters, timers, CRC engines, or protocol accelerators in hardware |
| USB Full-Speed Controller | On-die USB engine with descriptor handling and endpoint FIFOs - reduces firmware overhead vs. bit-banged solutions |
Applications
| Consumer Touch Remote | Industrial HMI Panel |
|---|---|
Use Scenario: Battery-powered universal remote with touch slider and gesture recognition. IC Role / Device Role / Timing Role: Main MCU executing CapSense® scanning, IR encoding, and low-power sleep/wake management. Use Value: Single-chip integration replaces discrete touch controller + microcontroller + USB bridge, reducing PCB area by 40% and BOM count by 7 parts. | Use Scenario: DIN-rail mounted operator interface with tactile feedback and real-time status display. IC Role / Device Role / Timing Role: Central controller managing button debouncing, LED dimming via PWM, and Modbus RTU over UART. Use Value: Programmable analog blocks condition 4–20 mA sensor inputs directly; UDBs implement custom protocol state machines without FPGA. |
| Medical Patient Monitor Button | Smart Home Appliance Control |
Use Scenario: Sterilizable touch panel on infusion pump with liquid-tolerant overlay. IC Role / Device Role / Timing Role: Dedicated CapSense® subsystem handles wet-finger detection and ESD-robust button scanning at 100 Hz update rate.

IC Role / Device Role / Timing Role: Mixed-signal controller managing CapSense® input, triac firing timing, and thermal shutdown monitoring. Use Value: Integrated high-voltage GPIO drivers (up to 25 V) directly interface with triac gate circuits, eliminating level-shifting components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C3866AXI-066 | Same PSoC 3 architecture, 66-pin QFN, 64 KB flash, no USB PHY | Lacks integrated USB transceiver - requires external USB bridge for host connectivity | Select when USB is not required and lower cost or smaller footprint is prioritized |
| PSoC 4200DS (CY8C4247LQI-M485) | ARM Cortex-M0+, 256 KB flash, 32 KB SRAM, CapSense® v4.0, USB FS | Higher performance CPU, newer CapSense® algorithm, but higher power in active mode | Select for new designs needing ARM ecosystem compatibility and extended peripheral set |
Compared with CY8C3MFIDOCK-128, CY8C3866AXI-066 trades USB integration for reduced pin count and cost, while CY8C4247LQI-M485 offers ARM-based scalability at the expense of legacy PSoC 3 toolchain continuity and higher active current.
