Product details
Overview
C167CRLMHABXUMA2 from Infineon Technologies is a 16-bit single-chip microcontroller with 128 KB on-chip mask ROM, 2 KB XRAM, and 2 KB IRAM, operating at 25 MHz CPU clock (40 ns instruction cycle), featuring integrated CAN 2.0B interface, 16-channel 10-bit ADC (7.8 µs conversion time), and dual CAPCOM units for motor control in industrial drives.
For engineers reviewing the C167CRLMHABXUMA2 datasheet, C167CRLMHABXUMA2 pinout, C167CRLMHABXUMA2 application, or C167CRLMHABXUMA2 equivalent, key selection criteria include CAN message object count (15), external bus support (16 MB address space), PLL clock multiplication factors (1.5× to 5×), and BGA-176 package thermal performance for high-density embedded control designs.
Technical Context
The C167CRLMHABXUMA2 implements a 4-stage pipelined C166-core CPU with register-based architecture, single-cycle context switching, and 16 Mbyte linear address space shared across code and data. Its peripheral set is optimized for real-time motion control: two 16-channel CAPCOM units support edge-aligned and center-aligned PWM generation, while the 4-channel PWM module provides dead-time insertion and fault protection inputs.
Integrated CAN 2.0B controller supports full CAN and Basic CAN modes with 15 configurable message objects, programmable bit timing, and automatic retransmission. The A/D converter features 16 selectable input channels, software- or event-triggered conversion, and programmable sample-and-hold timing down to 7.8 µs - enabling precise current sensing in servo amplifier feedback loops.

FAQ
What is the maximum operating temperature range for C167CRLMHABXUMA2?
The C167CRLMHABXUMA2 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 2.2 of the V3.3 datasheet, which specifies thermal derating curves and junction temperature limits up to +125 °C under defined PCB copper area and airflow conditions.
Does this MCU support in-system programming (ISP) via its on-chip bootloader?
Yes-the C167CRLMHABXUMA2 includes an on-chip bootstrap loader activated via UART0 using a specific hardware handshake (P3.0 = low at reset). It supports firmware upload in Intel HEX format and verifies checksums before writing to external Flash or internal ROM shadow regions, as documented in Section 3.15 of the datasheet.
Can the 10-bit ADC operate synchronously with PWM events?
Yes-the ADC supports event-triggered conversion using CAPCOM or GPT timer match events. Section 3.8 confirms that the ADCTRIG register allows direct linkage of ADC start-of-conversion to PWM center-aligned zero-crossing or edge events, enabling precise current sampling at motor phase-current null points.
Is the CAN module compliant with ISO 11898-1 (High-Speed CAN)?
The on-chip CAN controller implements protocol layer compliance with CAN 2.0B specification but requires an external physical-layer transceiver (e.g., TJA1040 or PCA82C251) for ISO 11898-1 electrical compliance. The C167CRLMHABXUMA2's CANTX/CANRX pins are digital-level only and do not drive differential bus lines directly.
