Product details
Overview
XC2288I136F128LAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Premium Line, featuring a five-stage pipeline CPU running at 128 MHz (7.8 ns instruction cycle), 1088 KB on-chip Flash, 24 KB DSRAM, and integrated MultiCAN (6 nodes, 256 message objects). It serves as a real-time control unit in automotive powertrain and chassis systems requiring deterministic timing, memory protection, and CAN-based communication.
For engineers reviewing the XC2288I136F128LAAKXUMA1 datasheet, XC2288I136F128LAAKXUMA1 pinout, XC2288I136F128LAAKXUMA1 application, or XC2288I136F128LAAKXUMA1 equivalent, key selection considerations include its 144-pin LQFP package, 3.0–5.5 V supply range, ECC-protected Flash/SRAM, dual 12-bit ADCs with <1 µs conversion, and TriCore-compatible instruction set for safety-critical embedded control.
Technical Context
The XC2288I136F128LAAKXUMA1 implements a TriCore-compatible CPU core with MPU, 16 KB ICache, and hardware CRC checker for memory supervision. Its interrupt system supports 112 nodes across 16 priority levels, with Peripheral Event Controller enabling single-cycle data transfers using 24-bit address pointers.
On-chip peripherals include two synchronizable 12-bit ADCs (24 channels), six general-purpose timers, CAPCOM2 (16-channel), CCU6x (up to four units for PWM), MultiCAN Rev. 2.0B (6 nodes), and USIC modules configurable as UART/LIN/SPI/I²C/IIS - all operating under a unified clock tree derived from internal PLL or external crystal.
Key Specifications

FAQ
What is the maximum operating frequency and associated instruction cycle time?
The XC2288I136F128LAAKXUMA1 operates at a maximum CPU clock of 128 MHz, delivering a 7.8 ns instruction cycle time for single-cycle execution of most arithmetic and logical operations. This timing is guaranteed under specified voltage (3.0–5.5 V) and temperature (–40 °C to +125 °C) conditions per AEC-Q100 Grade 1.
Does this microcontroller support functional safety standards like ISO 26262?
Yes - the XC2288I136F128LAAKXUMA1 includes hardware features required for ASIL-B compliance: Memory Protection Unit (MPU), Error Correction Code (ECC) for Flash and SRAM, hardware CRC checker, lock-step capable architecture (via TriCore compatibility), and diagnostic-capable peripherals such as ADC self-test and watchdog timers.
