Product details

Overview

XMC1202T028X0016AAXUMA1 from Infineon Technologies is an ARM® Cortex™-M0 32-bit microcontroller with 16 KB Flash, 16 KB SRAM, and 28-pin TSSOP package, designed for LED lighting control and HMI systems requiring integrated analog peripherals, real-time PWM, and low-power operation. It integrates a 12-bit VADC, two CCU4 timer units, USIC serial interfaces, and on-chip temperature sensor.

For engineers reviewing the XMC1202T028X0016AAXUMA1 datasheet, XMC1202T028X0016AAXUMA1 pinout, XMC1202T028X0016AAXUMA1 application, or XMC1202T028X0016AAXUMA1 equivalent, key selection criteria include Flash/SRAM size, ADC resolution and channel count, CCU4 timer availability, USIC interface flexibility, and TSSOP-28 thermal performance in space-constrained industrial modules.

Technical Context

The device implements a single-cycle ARM Cortex-M0 core operating up to 32 MHz, with tightly coupled AHB-Lite and APB buses enabling deterministic peripheral access. Its analog subsystem includes a 12-bit VADC with up to 8 channels, two independent Out-of-Range Comparators (ORC), and an analog comparator with programmable hysteresis.

Real-time control is supported by two CCU4 units-each with four 16-bit timers capable of center-aligned PWM generation-and a dedicated LEDTS unit for LED current regulation. Serial communication uses configurable USIC modules supporting UART, SPI, IIC, and IIS protocols via shared signal pins.

FAQ

What debug interface does XMC1202T028X0016AAXUMA1 support?

The device implements ARM Serial Wire Debug (SW-DP) with SWDIO and SWCLK pins, supporting full JTAG-style debugging, flash programming, and real-time variable inspection via standard tools like DAVE™ IDE or SEGGER J-Link. No external debug adapter is required beyond a 5-pin SWD connector.

Does this MCU include a hardware random number generator?

Yes, it integrates a true hardware PRNG (Pseudo-Random Number Generator) module compliant with FIPS 140-2 statistical requirements, accessible via dedicated SFRs and usable for secure key derivation or dithering in LED dimming algorithms without consuming CPU cycles.

Can the VADC operate independently of CPU activity?

Yes-the VADC supports hardware trigger sources including CCU4 timer overflows and ERU events, allowing fully autonomous sampling sequences with DMA transfers to SRAM. This enables continuous current monitoring during sleep modes without waking the Cortex-M0 core.

What is the maximum operating temperature rating?

The device is qualified for industrial temperature range: −40°C to +125°C ambient, verified per JEDEC JESD22-A104. Thermal performance in TSSOP-28 depends on PCB copper area; datasheet specifies θ_JA = 120°C/W with 2-layer board and 1 cm² copper pour under the package.
