XMC1402T038X0200AAXUMA1

Product Overview

The Infineon Technologies XMC1402T038X0200AAXUMA1 is a 32-bit microcontroller from the XMC1000 series. It is built around an ARM Cortex-M0 core with a 48 MHz operating speed, 200 KB (200K x 8) FLASH program memory, and 16K x 8 RAM. The device provides 26 I/O pins and integrates I2C, LINbus, SPI, and UART/USART connectivity. Analog and control functions include a 12 x 12-bit ADC, PWM, DMA, I2S, brown-out detect/reset, POR, and WDT. It operates from a 1.8 V to 5.5 V supply and uses a PG-TSSOP-38-9 surface-mount package.

Key Features

• ARM Cortex-M0 32-bit core operating at 48 MHz
• 200 KB (200K x 8) FLASH program memory and 16K x 8 RAM
• 26 I/O pins in a 38-TFSOP surface-mount package with 4.40 mm body width
• I2C, LINbus, SPI, and UART/USART serial connectivity
• Brown-out detect/reset, DMA, I2S, POR, PWM, and WDT peripherals
• 12 x 12-bit ADC and internal oscillator
• 1.8 V to 5.5 V supply range and -40°C to 105°C operating temperature range (TA)

Applications

• Embedded control subsystems requiring 32-bit processing, FLASH program memory, and 26 I/O
• Analog sensor measurement paths using the 12 x 12-bit ADC
• Pulse-width modulated control output generation
• Serial communication integration using I2C, SPI, UART/USART, or LINbus

Design & Procurement Notes

Design planning should start with the 200 KB FLASH and 16K x 8 RAM memory budget, the 48 MHz core speed, and the available 26 I/O pins. The 1.8 V to 5.5 V supply range and -40°C to 105°C (TA) operating range define power and ambient thermal boundaries. The PG-TSSOP-38-9, 38-TFSOP surface-mount package requires a footprint matched to the 4.40 mm body width. The internal oscillator provides an on-chip clock source, and timing-critical designs should verify clock accuracy against the application. Peripheral allocation for I2C, LINbus, SPI, UART/USART, ADC, PWM, DMA, I2S, POR, WDT, and brown-out detect/reset should be mapped before finalizing the pin plan.
