Infineon Technologies XC2310S8F40RAAKXUMA1

Overview

XC2310S8F40RAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Compact Line, featuring a five-stage pipeline CPU delivering 32-bit performance at 66 MHz (15.2 ns instruction cycle), 64 KB on-chip Flash, 8 KB SRAM (2 KB DPRAM + 2 KB DSRAM + 4 KB PSRAM), and integrated peripherals including CCU60 PWM unit, 12-bit A/D converter (≤1 μs conversion), and UART/LIN/SPI/I²C/USIC interfaces. It targets automotive body control, industrial motor control, and embedded real-time systems requiring deterministic timing and memory protection.

For engineers reviewing the XC2310S8F40RAAKXUMA1 datasheet, XC2310S8F40RAAKXUMA1 pinout, XC2310S8F40RAAKXUMA1 application, or XC2310S8F40RAAKXUMA1 equivalent, key selection criteria include its 66 MHz CPU clock with MPU, ECC-protected Flash, dual-port RAM architecture, and support for safety-critical operation via hardware CRC checker and window watchdog timer.

Technical Context

The XC2310S8F40RAAKXUMA1 implements the C166™-compatible 16/32-bit CPU core with five-stage pipeline, zero-cycle jumps, and MAC instructions, enabling deterministic real-time execution. Its memory subsystem includes ECC-protected 64 KB Flash, parity-protected SRAM blocks, and a Memory Protection Unit (MPU) supporting up to 16 regions with read/write/execute permissions.

Peripheral integration centers on time-critical control: the CCU60 unit provides flexible PWM generation with dead-time insertion and emergency shutdown, while the 12-bit A/D converter supports broken-wire detection and range-check preprocessing. Clocking uses an internal PLL with external crystal or oscillator input, and wake-up from low-power modes occurs in ≤15.2 ns.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time of the XC2310S8F40RAAKXUMA1?

The XC2310S8F40RAAKXUMA1 operates at a maximum CPU clock frequency of 66 MHz, yielding a 15.2 ns instruction cycle time. This timing is achieved using the on-chip PLL with external crystal input and is validated across the full –40°C to +125°C temperature range per its SAK-grade qualification.

Does the XC2310S8F40RAAKXUMA1 support functional safety standards such as ISO 26262?

Yes-the device includes hardware features aligned with ASIL-B requirements: ECC-protected Flash memory, parity-protected SRAM, Memory Protection Unit (MPU), hardware CRC checker, window watchdog timer, and lockstep-capable debug interfaces. While not pre-certified, it provides the foundational mechanisms required for ASIL-B system-level certification.

How many A/D converter channels does the XC2310S8F40RAAKXUMA1 support, and what is the minimum conversion time?

The XC2310S8F40RAAKXUMA1 integrates an 8-channel, 12-bit successive-approximation A/D converter with a guaranteed maximum conversion time of 1 μs. It supports hardware-triggered sampling, broken-wire detection, and programmable range checking for sensor signal validation.

What debug interfaces are supported, and is JTAG the only option?

The XC2310S8F40RAAKXUMA1 supports three standardized debug interfaces: IEEE 1149.1 JTAG, Single-Pin DAP (SPD), and Device Access Port (DAP). All provide full visibility into CPU state, memory, and peripherals; SPD enables debugging with minimal pin count, while DAP supports high-speed flash programming and real-time trace.
