Infineon Technologies XC822MT1FRAAAKXUMA1

Overview

XC822MT1FRAAAKXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the 8051 instruction set and executing instructions at two clocks per machine cycle. It integrates 2 KB Flash memory, 256 bytes RAM, 256 bytes XRAM, a 10-bit 4-channel ADC with differential input support, and a 16-bit CCU6 for PWM generation. It operates across -40 °C to 125 °C (SAK grade) and targets automotive body electronics and industrial sensor control.

For engineers reviewing the XC822MT1FRAAAKXUMA1 datasheet, XC822MT1FRAAAKXUMA1 pinout, XC822MT1FRAAAKXUMA1 application, or XC822MT1FRAAAKXUMA1 equivalent, key selection criteria include its embedded voltage regulator supplying core logic at 2.5 V while supporting I/O at 2.5–5.5 V, integrated LED/touch-sense controller (LEDTSCU), and single-pin debug interface (SPD) for space-constrained embedded designs.

Technical Context

The XC822MT1FRAAAKXUMA1 implements a two-clock-per-cycle 8051-compatible core with dual data pointers and on-chip debug via SPD. Its memory subsystem includes 2 KB Flash with protection, 8 KB ROM (Boot/Library/User), 256 bytes RAM, and 256 bytes XRAM - enabling self-contained firmware execution without external memory.

Peripherals are tightly coupled to real-time control: the 16-bit CCU6 supports center-aligned PWM for motor drive; the 10-bit ADC offers configurable filtering yielding up to 13-bit effective resolution; and the LEDTSCU provides capacitive touch sensing with hardware-accelerated scanning, eliminating host CPU overhead in HMI applications.

FAQ

What is the maximum operating frequency of the XC822MT1FRAAAKXUMA1 core?

The XC822MT1FRAAAKXUMA1 uses an on-chip 48 MHz RC oscillator as its primary clock source. The XC800 core executes instructions at two clocks per machine cycle, delivering an effective throughput of 24 MIPS. No external crystal is required for full-speed operation, though optional external clock sources up to 48 MHz are supported via the OSCIN pin.

Does XC822MT1FRAAAKXUMA1 support in-system programming (ISP)?

Yes, XC822MT1FRAAAKXUMA1 supports ISP via the single-pin SPD interface using Infineon's DAP protocol. Firmware updates can be performed in-circuit without removing the device, with Flash memory protected by lock bits that prevent unauthorized read/write access during normal operation.

How many analog input channels does the integrated ADC support?

The ADC supports four single-ended analog inputs (ADC0–ADC3), with up to three configured as differential pairs (e.g., ADC0/ADC1, ADC2/ADC3). Each channel can be sampled at up to 100 kSPS, and results are processed by an on-chip digital low-pass filter to achieve up to 13-bit effective resolution.

Is the LEDTSCU capable of simultaneous LED driving and touch sensing?

Yes, the LED and Touch-Sense Controller (LEDTSCU) operates in time-multiplexed mode: it drives up to four LEDs with programmable brightness during active display periods, then switches to capacitive sensing on the same pins during dedicated scan windows - all autonomously without CPU intervention.
