Infineon Technologies XC167CI32F40FBBAFXUMA1

Overview

XC167CI32F40FBBAFXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 256 KB on-chip Flash, 12 KB total SRAM (2 KB DPRAM + 4 KB DSRAM + 6 KB PSRAM), and integrated TwinCAN, ASC/SSC serial interfaces, and a 16-channel 10-bit ADC with 2.55 µs conversion time. It operates at 40 MHz CPU clock (25 ns instruction cycle) and supports automotive-grade temperature range (−40 °C to 125 °C) in a 144-pin RoHS-compliant TQFP package.

For engineers reviewing the XC167CI32F40FBBAFXUMA1 datasheet, XC167CI32F40FBBAFXUMA1 pinout, XC167CI32F40FBBAFXUMA1 application, or XC167CI32F40FBBAFXUMA1 equivalent, key selection criteria include CAN 2.0B dual-node support, on-chip PLL clock generation (1:0.15–1:10), peripheral event controller (PEC)-driven DMA, real-time clock with dedicated oscillator, and JTAG-based on-chip debug support (OCDS).

Technical Context

The XC167CI32F40FBBAFXUMA1 implements a 5-stage pipelined C166SV2 CPU core with zero-cycle jumps, 1-cycle 16×16 multiplication, and MAC instructions-enabling deterministic real-time control. Its memory subsystem includes separate 2 KB dual-port RAM for concurrent CPU/peripheral access and 256 KB Flash with configurable wait states (IMBCTRL.WSFLASH) for 40 MHz operation.

Peripheral integration centers on deterministic timing: TwinCAN supports 32 message objects across two independent CAN nodes with gateway functionality; CAPCOM6 provides flexible PWM generation with 3/6 capture/compare channels; GPT12E delivers five timers with programmable prescalers; and the 16-channel ADC achieves 10-bit resolution with selectable conversion speed (2.55 µs min) and hardware-triggered sampling.

Key Specifications

Pinout & Package

XC167CI32F40FBBAFXUMA1 is housed in a 144-pin Thin Quad Flat Package (TQFP) with 0.5 mm lead pitch, RoHS-compliant green molding compound, and thermal pad exposed on underside for enhanced heat dissipation (RΘJC = 12.5 K/W). Pin definitions follow Infineon's standardized XC167CI pin mapping for derivative SAK-XC167CI-32F40F.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time for XC167CI32F40FBBAFXUMA1?

The XC167CI32F40FBBAFXUMA1 supports a maximum CPU clock frequency of 40 MHz, achieving a 25 ns instruction cycle time under single-cycle execution conditions. This performance is enabled by its 5-stage pipelined C166SV2 core and on-chip PLL configured for 1:10 multiplication from a 4 MHz crystal. Wait-state configuration (via IMBCTRL.WSFLASH) must be set correctly to ensure reliable Flash access at this speed.

Does XC167CI32F40FBBAFXUMA1 support CAN FD or only classical CAN 2.0B?

The XC167CI32F40FBBAFXUMA1 implements TwinCAN compliant with ISO 11898-1 Revision 2.0B only-it does not support CAN FD (Flexible Data-Rate). It provides two independent CAN nodes with 32 total message objects, full/basic CAN operation, and hardware-accelerated message filtering and gateway routing between nodes, but lacks the higher bit rates (up to 5 Mbit/s) and extended data length (64 bytes) of CAN FD.

How is the ADC triggered, and what is the minimum conversion time in 10-bit mode?

The 16-channel ADC supports both software-triggered and hardware-triggered conversions, with dedicated ADCTRIGx pins accepting edge-sensitive signals from CAPCOM units or GPT12E timers for precise synchronous sampling. In 10-bit resolution mode, the minimum conversion time is 2.55 µs, verified under specified supply and temperature conditions per Data Sheet Section 4.3. This timing enables up to ~392 kSPS aggregate throughput with proper channel sequencing.

Is JTAG debugging supported, and what debug capabilities does OCDS provide?

Yes, XC167CI32F40FBBAFXUMA1 includes On-Chip Debug Support (OCDS) accessible via standard JTAG interface (IEEE 1149.1). OCDS provides real-time trace, non-intrusive breakpoints, register visibility, and memory access without halting CPU execution-critical for validating timing-critical control loops. TRST signal behavior was updated in Data Sheet V1.1 (p.13) to improve debug initialization robustness.
