Infineon Technologies XC836M1FRIABFXUMA1

Overview

XC836M1FRIABFXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the high-performance XC800 core (8051-compatible, two-clock-per-machine-cycle), featuring 8 KB Flash, 256 bytes RAM, 10-bit 8-channel ADC with differential input support, and integrated LED/touch-sense controller. It operates across -40 °C to 125 °C (SAK grade) and targets motor control, appliance HMI, and embedded sensing applications.

For engineers reviewing the XC836M1FRIABFXUMA1 datasheet, XC836M1FRIABFXUMA1 pinout, XC836M1FRIABFXUMA1 application, or XC836M1FRIABFXUMA1 equivalent, key selection criteria include its on-chip 48 MHz oscillator with loss-of-clock detection, 16-bit CCU6 PWM unit, real-time clock with 32.768 kHz crystal pad, and single-pin SPD debug interface for space-constrained designs.

Technical Context

The XC836M1FRIABFXUMA1 integrates a dual-supply architecture: I/O ports operate at 2.5–5.5 V while core logic runs at a regulated 2.5 V. Its XC800 core delivers zero-wait-state memory access via two data pointers and supports fixed-point control algorithms using the embedded MDU and CORDIC units.

Peripheral integration includes a 16-bit Capture/Compare Unit (CCU6) for field-oriented motor control, an 8-channel SSC interface configurable as master or slave, and an LED/TSCU module supporting up to 16 capacitive touch channels and LED dimming without external components.

FAQ

Does XC836M1FRIABFXUMA1 support in-system programming via SPD?

Yes. The SPD interface supports full in-system programming (ISP) and debugging using a single pin and standard UART-level voltage levels. Firmware updates can be performed without removing the device from the PCB, and the protocol includes CRC-based packet validation to ensure programming integrity during field upgrades.

What is the maximum ADC sampling rate with digital filtering enabled?

The 10-bit ADC achieves up to 100 kSPS in single-shot mode. When digital low-pass filtering is enabled (averaging 4–16 samples), effective throughput drops to 25–50 kSPS, but resolution improves to up to 13 bits for noise-sensitive applications like current sensing in motor phases.

Can the CCU6 unit generate complementary PWM outputs with programmable dead time?

Yes. CCU6 supports center-aligned and edge-aligned PWM modes with hardware-configurable dead-time insertion (1–128 clock cycles) between complementary outputs. This ensures safe switching of high-side/low-side MOSFETs in half-bridge configurations without software overhead or timing jitter.

Is the 48 MHz on-chip oscillator stable enough for UART communication at 115.2 kbps?

Yes. The 48 MHz RC oscillator has ±2 % accuracy over -40 °C to +125 °C and ±1 % over 0 °C to +70 °C, meeting UART timing tolerance requirements for 115.2 kbps (±3 % max error). No calibration is required for standard baud rates in industrial environments.
