Product details
Overview
XC2236N40F66LAAFXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Family / Value Line, featuring a C166-compatible CPU core with 80 MHz operation (12.5 ns instruction cycle), 320 KB on-chip Flash memory, 16 KB PSRAM, and integrated MultiCAN 2.0B interface with up to 6 CAN nodes. It supports automotive powertrain control, motor drive timing, and industrial real-time I/O management.
For engineers reviewing the XC2236N40F66LAAFXUMA1 datasheet, XC2236N40F66LAAFXUMA1 pinout, XC2236N40F66LAAFXUMA1 application, or XC2236N40F66LAAFXUMA1 equivalent, key selection criteria include Flash endurance (100k cycles), ECC-protected memory architecture, dual A/D converters (10-bit, <1 μs conversion), CCU6x PWM units for motor control, and JTAG/DAP debug support.
Technical Context
The XC2236N40F66LAAFXUMA1 implements a five-stage pipelined C166 CPU core with MPU, supporting 16 MB linear address space and fast context switching via two local register banks. It integrates a hardware CRC checker with programmable polynomial for memory integrity verification and an on-chip Memory Protection Unit enforcing privilege-level access control.
Its peripheral set includes two synchronizable 10-bit A/D converters with broken-wire detection, six USIC channels configurable as UART/LIN/SPI/I²C/IIS, and a MultiCAN module with 256 message objects across six CAN nodes - all operating under a unified clock domain derived from a configurable PLL with internal/external source selection.

FAQ
What is the maximum operating temperature range for XC2236N40F66LAAFXUMA1?
The XC2236N40F66LAAFXUMA1 is rated for operation from –40 °C to +110 °C (SAH-grade), validated per Infineon's industrial and automotive qualification standards. This range supports under-hood automotive applications and industrial environments with elevated ambient temperatures.
Does XC2236N40F66LAAFXUMA1 support in-system programming via CAN?
Yes - it includes an on-chip bootstrap loader that supports firmware updates over CAN using standardized UDS (ISO 14229) diagnostic services. The MultiCAN module handles message filtering and buffer management, enabling secure, authenticated reprogramming without external tools.
Is ECC enabled by default on all on-chip memory regions?
ECC is hardware-enabled for Flash and PSRAM during normal operation; SBRAM and DPRAM support optional ECC activation via MPU configuration registers. Error correction is automatic and transparent, with uncorrectable errors triggering NMI for system-level fault handling.
Can the CCU6x modules generate complementary PWM outputs with programmable dead time?
Yes - each CCU6 unit supports center-aligned and edge-aligned complementary PWM pairs with independent dead-time insertion (adjustable in 1–255 clock cycles). Dead-time values are stored in dedicated shadow registers and updated synchronously with PWM period reload.
