Product details
Overview
XE161FL12F80VAAFXUMA1 from Infineon Technologies is a 16-bit real-time signal controller in the XE166 Family Econo Line, featuring an 80 MHz C166-compatible CPU with five-stage pipeline, 160 KB on-chip Flash, 12-bit ADC (10 channels, <1 µs conversion), and dual CAN 2.0B nodes. It operates from 3.0–5.5 V and targets motor control and industrial automation systems requiring deterministic timing and integrated peripherals.
For engineers reviewing the XE161FL12F80VAAFXUMA1 datasheet, XE161FL12F80VAAFXUMA1 pinout, XE161FL12F80VAAFXUMA1 application, or XE161FL12F80VAAFXUMA1 equivalent, key selection criteria include its 80 MHz instruction cycle time (12.5 ns), on-chip MultiCAN with 32 message objects, CCU6x PWM units for motor drive, and 48-pin VQFN package with 33 GPIO lines.
Technical Context
The XE161FL12F80VAAFXUMA1 implements a C166v2 CPU core with MPU, supporting 16 Mbyte linear addressing, fast context switching via dual local register banks, and zero-cycle jumps. Its memory subsystem includes 2 KB DPRAM, 6 KB DSRAM, 4 KB PSRAM, and ECC-protected 160 KB Flash - all accessible within a single-cycle data path.
Peripheral integration centers on real-time signal processing: the 12-bit ADC supports broken-wire detection and range-check preprocessing; CCU6x units deliver complementary PWM with dead-time control; and the MultiCAN module enables gateway functionality across two independent CAN nodes with full CAN/BASIC CAN support.

FAQ
What is the maximum operating temperature range for XE161FL12F80VAAFXUMA1?
The XE161FL12F80VAAFXUMA1 is rated for operation from –40 °C to +85 °C, as indicated by the "VAA" suffix in the ordering code. This industrial temperature grade is validated per Infineon's reliability testing in Data Sheet Section 5.2 and applies under specified supply voltage and load conditions.
Does XE161FL12F80VAAFXUMA1 support in-system programming via CAN?
Yes - the on-chip bootstrap loader supports firmware updates over CAN bus using standard CAN 2.0B frames. The bootloader resides in protected ROM and activates upon specific CAN ID reception, enabling field upgrades without physical access or JTAG hardware.
How many independent PWM output channels does this MCU provide?
The XE161FL12F80VAAFXUMA1 integrates two CCU6x modules, each delivering three complementary PWM outputs with dead-time control and fault blanking - totaling six independent, phase-shifted PWM channels suitable for 3-phase inverter gate drive.
Is the 12-bit ADC capable of simultaneous sampling across multiple channels?
No - the single 12-bit ADC supports sequential sampling across up to 10 channels with configurable scan sequences and hardware-triggered start, but lacks true simultaneous sampling. However, conversion time remains below 1 µs per channel, enabling tightly interleaved acquisition for multi-sensor feedback loops.
