Infineon Technologies XC836MT2FRAABKXUMA1

Overview

XC836MT2FRAABKXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, featuring 8 KB Flash, 256 bytes RAM, and integrated 10-bit 8-channel ADC. It includes a 48 MHz on-chip oscillator, real-time clock with 32.768 kHz crystal pad, and CCU6 capture/compare unit for PWM generation. Used in motor control subsystems requiring field-oriented control support via embedded CORDIC and MDU units.

For engineers reviewing the XC836MT2FRAABKXUMA1 datasheet, XC836MT2FRAABKXUMA1 pinout, XC836MT2FRAABKXUMA1 application, or XC836MT2FRAABKXUMA1 equivalent, key selection criteria include on-chip oscillator stability, 16-bit vector computation capability, differential ADC channel count, RTC wake-up timing, and PG-TSSOP-28 package compatibility with industrial thermal cycling requirements.

Technical Context

The XC836MT2FRAABKXUMA1 implements an enhanced 8051-compatible XC800 core with two-clock-per-machine-cycle execution and dual data pointers, enabling zero-wait-state memory access. It integrates dedicated hardware accelerators: a 16-bit CORDIC unit for sine/cosine/tangent computation and an MDU for fixed-point multiplication/division - both essential for real-time field-oriented motor control.

Its peripheral set includes a 16-bit CCU6 unit supporting center-aligned and edge-aligned PWM with dead-time insertion, three 16-bit timers (T0/T1/T2), and a programmable watchdog timer with independent oscillator and windowed refresh. The 10-bit ADC supports up to 7 differential input channels with digital low-pass filtering yielding up to 13-bit effective resolution.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the on-chip oscillator?

The XC836MT2FRAABKXUMA1 features a factory-calibrated 48 MHz on-chip RC oscillator with ±2% accuracy over temperature and voltage. This clock feeds the XC800 core directly and supports all peripherals without external crystal dependency, though optional external crystals may be used for higher precision timing paths such as RTC.

Does this MCU support hardware-based field-oriented control (FOC)?

Yes-it integrates dedicated hardware blocks: a 16-bit CORDIC unit for real-time sine/cosine/arctan computation and an MDU for fast fixed-point multiplication/division. These enable full FOC loop execution-including Clarke/Park transforms and PI current regulation-in under 1 µs per phase, eliminating reliance on software libraries or external DSPs.

What debug interface does XC836MT2FRAABKXUMA1 use?

It uses a single-pin Serial Debug Port (SPD) compliant with Infineon's DAP protocol, supporting non-intrusive flash programming, real-time variable observation, and breakpoint debugging without dedicated JTAG pins. The SPD interface operates at up to 1 Mbps and requires only one GPIO plus ground.

Is the RTC functional in power-down mode?

Yes-the real-time clock continues running from the 32.768 kHz crystal during power-down mode, consuming less than 1.2 µA. It can generate periodic wake-up interrupts at intervals from 16 ms to 256 s, enabling energy-efficient timed operations such as sensor polling or system health checks.
