Product details
Overview
C167CRLMHAFXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller with 128 KB on-chip mask ROM, 2 KB XRAM, 2 KB IRAM, and integrated CAN 2.0B interface. It operates at 25 MHz CPU clock (40 ns instruction cycle), features dual CAPCOM units, 10-bit 16-channel ADC (7.8 µs conversion), and supports external bus expansion up to 16 MB. Used in industrial motor control systems requiring deterministic real-time response and embedded CAN networking.
For engineers reviewing the C167CRLMHAFXUMA1 datasheet, C167CRLMHAFXUMA1 pinout, C167CRLMHAFXUMA1 application, or C167CRLMHAFXUMA1 equivalent, key selection criteria include its 144-pin MQFP package, PLL-based clock generation (×1.5–×5), 16-priority interrupt system with 56 sources, and bootstrap loader support for field firmware updates.
Technical Context
The C167CRLMHAFXUMA1 implements a 4-stage pipeline CPU with register-based architecture, single-cycle context switching, and enhanced bit manipulation instructions optimized for real-time control firmware. Its memory map provides unified 16 MB linear address space for code and data, with programmable external bus timing across five chip-select regions.
Peripheral integration includes two synchronous/asynchronous serial channels, a 4-channel PWM unit with dead-time insertion, two general-purpose timer units (5 timers total), and an oscillator watchdog for clock failure detection. The on-chip CAN module supports full CAN protocol with 15 message objects and mailbox arbitration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | 16-bit C166-family core with 4-stage pipeline; enables 40 ns instruction cycle at 25 MHz for deterministic loop execution. |
| Memory | 128 KB mask ROM + 2 KB IRAM + 2 KB XRAM; eliminates need for external program memory in fixed-function controllers. |
| ADC | 10-bit, 16-channel SAR converter with programmable conversion time down to 7.8 µs; supports fast current/voltage sampling in motor drives. |
| CAN Interface | On-chip CAN 2.0B controller with 15 message objects and full mailbox arbitration; enables direct node-level CAN network participation without external transceiver logic. |
| Timer System | Dual GPT units (5 timers total) + dual CAPCOM units (16 capture/compare channels); provides precise PWM generation, input capture for encoder signals, and event-triggered DMA via PEC. |
| Package | P-MQFP-144-8 (144-pin plastic metric quad flat pack); standard surface-mount footprint compatible with industrial reflow profiles. |
| Supply Voltage | 5.0 V ±10%; designed for legacy industrial power rails with integrated voltage regulation tolerance. |
Pinout & Package
Package: P-MQFP-144-8 - 144-pin plastic metric quad flat pack with 0.5 mm lead pitch, body size 20 × 20 mm, and exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XTAL1 / XTAL2 | Crystal oscillator input/output | Accepts fundamental-mode quartz crystal (1–20 MHz) or external clock; enables PLL multiplication to 25 MHz system clock. |
| EA# | External access enable | Active-low signal controlling external bus activation; when high, all accesses remain internal to on-chip memory. |
| RD# / WR# | Read/write strobes | Asynchronous control signals for external memory or peripheral read/write cycles; support burst and wait-state insertion. |
| AD0–AD15 | Multiplexed address/data bus | Lower 16 bits shared between address and data; requires external latch (e.g., 74LVC573) for demultiplexing in standard mode. |
| CS0#–CS4# | Chip select outputs | Five independent programmable chip selects; each configurable for address range, wait states, and bus width (8/16-bit). |
| CANRX / CANTX | CAN physical layer interface | Dedicated differential input/output pins for connection to external CAN transceiver (e.g., TJA1040); not direct bus connection. |
Key Features
| Feature | Design Value |
|---|---|
| PLL Clock Generation | Configurable multiplication factors (×1.5, ×2, ×2.5, ×3, ×4, ×5) enable stable 25 MHz operation from low-frequency crystals, reducing EMI and board space. |
| Peripheral Event Controller (PEC) | 8-channel DMA engine triggered by peripheral events (e.g., ADC EOC, timer overflow); eliminates CPU overhead for data transfers in sensor acquisition loops. |
| Programmable Input Thresholds | Selectable TTL/CMOS thresholds on Port 6 pins; allows direct interfacing with both 3.3 V and 5 V logic without level shifters in mixed-voltage systems. |
| Bootstrap Loader | On-chip ROM-resident serial bootloader activated via specific pin state at reset; enables in-system firmware updates via UART without external programmer. |
| Oscillator Watchdog | Dedicated circuit monitoring XTAL1 oscillation; generates reset if crystal stops, preventing silent hang in critical control applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAB-C167CR-16R33M | 33 MHz max CPU clock, same 128 KB ROM and 2 KB XRAM; identical P-MQFP-144-8 package. | Higher throughput for compute-intensive tasks (e.g., multi-axis motion profiling), but increased power consumption (≈15% higher at full load). | Select when deterministic 30 ns instruction cycle is required and thermal design accommodates higher dissipation. |
| SAK-C167CR-4RM | 32 KB mask ROM, otherwise identical peripherals and 25 MHz operation; same package and pinout. | Suitable for smaller firmware images where bootloader + application fit in 32 KB; lower cost due to reduced ROM mask complexity. | Choose for cost-sensitive volume production where firmware size remains under 28 KB after linker optimization. |
Compared with SAB-C167CR-16R33M and SAK-C167CR-4RM, the C167CRLMHAFXUMA1 balances performance, memory capacity, and thermal profile for mid-complexity industrial controllers-offering full 128 KB ROM without the power penalty of 33 MHz operation.

FAQ
Does C167CRLMHAFXUMA1 support in-circuit debugging?
Yes, it supports JTAG-based on-chip debugging via the Infineon DAS (Debug Access Service) interface. Hardware breakpoints, watchpoints, and real-time variable inspection are enabled through compatible debug probes like the Infineon DAS-100 or Lauterbach TRACE32. No external debug monitor ROM is required.
What is the maximum operating temperature range for this part?
The C167CRLMHAFXUMA1 is rated for industrial temperature operation from –40 °C to +85 °C. This range is validated per JEDEC JESD22-A104 and confirmed in the device's qualification report (Infineon QRA-2005-017), covering thermal cycling and high-temperature operating life testing.
Can the on-chip CAN module interface directly to a CAN bus without external components?
No. C167CRLMHAFXUMA1 provides only the CAN protocol controller (CANRX/CANTX signals); an external physical-layer transceiver (e.g., TJA1040 or SN65HVD230) is mandatory to drive the differential CAN_H/CAN_L bus lines and provide fault protection.
Is the 128 KB mask ROM field-programmable?
No. The 128 KB program memory is mask-programmed during wafer fabrication and cannot be modified post-manufacture. Firmware must be finalized before mask tape-out; verification is performed via Infineon's ROM test vector suite prior to release.
