Infineon Technologies XC836MT2FRIABFXUMA1

Overview

XC836MT2FRIABFXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, featuring 8 KB Flash, 256 bytes RAM, 10-bit 8-channel ADC, and integrated CCU6 PWM unit. It operates at up to 48 MHz via on-chip oscillator and supports real-time clock with 32.768 kHz crystal input. Used in motor control subsystems requiring field-oriented control (FOC) execution.

For engineers reviewing the XC836MT2FRIABFXUMA1 datasheet, XC836MT2FRIABFXUMA1 pinout, XC836MT2FRIABFXUMA1 application, or XC836MT2FRIABFXUMA1 equivalent, key selection criteria include embedded MDU/CORDIC for FOC math acceleration, dual-supply I/O (2.5–5.5 V), brownout detection per supply domain, and SPD single-pin debug interface compatibility.

Technical Context

The XC836MT2FRIABFXUMA1 implements a two-clock-per-machine-cycle 8051-compatible core with dual data pointers and on-chip voltage regulator generating 2.5 V core supply from 2.5–5.5 V I/O rail. It integrates dedicated hardware accelerators: MDU for fixed-point multiplication/division and CORDIC for sine/cosine/arctan computation - both essential for real-time motor vector control loops.

Peripheral integration includes CCU6 for high-resolution center-aligned PWM generation, 8-channel 10-bit ADC with differential inputs and digital filtering (up to 13-bit effective resolution), and three independent 16-bit timers. The device supports wake-up from power-down mode via RTC alarm and features loss-of-clock detection on its 48 MHz internal oscillator.

FAQ

What is the maximum operating frequency of the XC836MT2FRIABFXUMA1 core?

The XC836MT2FRIABFXUMA1 uses an on-chip 48 MHz oscillator driving the XC800 core, which executes instructions at two clocks per machine cycle - delivering effective throughput equivalent to a 24 MHz standard 8051. This enables zero-wait-state access to on-chip Flash and RAM, critical for deterministic motor control loops.

Does XC836MT2FRIABFXUMA1 support hardware-based field-oriented control?

Yes - it integrates both a Multiplication/Division Unit (MDU) and a CORDIC co-processor, enabling full hardware acceleration of Park/Clarke transforms, PI regulators, and space-vector modulation calculations. These units operate independently of the main CPU, allowing FOC execution in under 1 µs per vector rotation without compromising main application task scheduling.

What debug interface does XC836MT2FRIABFXUMA1 use, and how many pins are required?

It uses the Serial Programming and Debug (SPD) interface, which requires only one dedicated pin (SPD) plus ground. This single-pin solution supports flash programming, real-time variable observation, breakpoint setting, and reset control - eliminating the need for multi-pin JTAG headers and reducing PCB routing complexity in space-constrained motor drive modules.

Is XC836MT2FRIABFXUMA1 qualified for automotive under-hood applications?

Yes - the "SAK" suffix denotes qualification for −40 °C to +125 °C ambient operation, meeting AEC-Q100 stress test requirements for Grade 2 automotive components. Its brownout detection on both I/O and core supplies, independent watchdog timer, and loss-of-clock monitoring provide necessary functional safety foundations for auxiliary pump and cooling fan controllers.
