Product details
Overview
C167CRL33MHAKXQLA1 from Infineon Technologies is a 16-bit single-chip microcontroller with 128 KB on-chip mask ROM, 2 KB XRAM, 33 MHz CPU clock, on-chip PLL (×1.5/2/2.5/3/4/5), and integrated CAN 2.0B interface supporting 15 message objects. It targets real-time industrial control systems requiring deterministic interrupt response, motor timing precision, and embedded networking.
For engineers reviewing the C167CRL33MHAKXQLA1 datasheet, C167CRL33MHAKXQLA1 pinout, C167CRL33MHAKXQLA1 application, or C167CRL33MHAKXQLA1 equivalent, key selection criteria include its 16-priority-level interrupt system (40 ns sample rate), 16-channel 10-bit ADC (7.8 µs conversion), dual CAPCOM units, and P-MQFP-144-8 package compatibility with legacy C166-family toolchains.
Technical Context
The C167CRL33MHAKXQLA1 implements a 4-stage pipeline CPU delivering 80 ns instruction cycle time at 33 MHz, with hardware-accelerated 16×16 multiply (303 ns) and 32÷16 divide (606 ns). Its memory map supports 16 MB linear address space, split across on-chip ROM/RAM and configurable external bus with five chip-selects.
Peripheral integration includes two synchronous/asynchronous serial channels, dual GPT units (5 timers total), 4-channel PWM, and a dedicated CAN 2.0B controller with full CAN message object management - all accessible via peripheral event controller (PEC) for single-cycle data transfers without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 33 MHz - enables 80 ns instruction cycle time for hard real-time loop execution in motor control. |
| ROM Size | 128 KB mask ROM - provides fixed, tamper-resistant firmware storage for safety-critical applications. |
| RAM Size | 2 KB XRAM + 2 KB IRAM - sufficient for stack, buffers, and real-time variable storage in compact embedded designs. |

Pinout & Package
Package: P-MQFP-144-8 (Plastic Metric Quad Flat Package, 144 leads, 0.5 mm pitch, 20 × 20 mm body).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XTAL1 / XTAL2 | Crystal oscillator input/output | Supports external crystal (1–20 MHz) or ceramic resonator; internal PLL multiplies to 33 MHz system clock. |
| EA | External access enable | Active-low signal controlling external memory bus activation - essential for boot mode selection and memory mapping. |
| AS | Address strobe | Indicates valid address on multiplexed bus; synchronizes external memory read/write timing during external bus cycles. |
| RXD0 / TXD0 | UART0 serial I/O | Asynchronous communication interface for debug, configuration, or host connectivity at up to 115.2 kbps. |
| CANRX / CANTX | CAN physical layer interface | Differential CAN bus connection points - require external transceiver (e.g., TJA1040) for ISO 11898 compliance. |
| P6.0–P6.7 | Port 6 general-purpose I/O | Bi-directional pins with programmable input thresholds and hysteresis - suitable for noisy industrial sensor interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle context switching | Enables rapid task switching in RTOS environments without register save/restore overhead. |
| Peripheral Event Controller (PEC) | Offloads DMA-like data movement (e.g., ADC → RAM) without CPU cycles, reducing jitter in time-critical loops. |
| Programmable watchdog timer | Configurable timeout period with windowed mode - prevents runaway code while allowing safe reset windows. |
| Oscillator watchdog | Monitors XTAL1 clock stability independently; triggers reset if crystal fails or drifts beyond ±20%. |
| Bootstrap loader | On-chip ROM-based serial bootloader allows field firmware updates via UART without external programmer. |

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 | Same die, identical electrical specs and pinout; differs only in ordering code format (SAB vs SAK prefix). | No functional difference - used interchangeably in production where Infineon's SAB-prefix logistics apply. | Select based on distributor stock and procurement channel alignment, not technical differentiation. |
| SAK-C167CR-16R33M | Identical mask ROM content, package, and timing; minor traceability marking variation per wafer lot. | Same use cases - deployed in identical industrial control boards where long-term availability of MQFP-144 footprint is required. | Preferred when matching original design BOMs referencing SAK-prefix nomenclature. |
Compared with SAB-C167CR-16R33M and SAK-C167CR-16R33M, C167CRL33MHAKXQLA1 shares identical silicon, timing, and peripheral functionality - differences are strictly logistical (marking, packaging, shipping documentation), not architectural or electrical.

FAQ
Does C167CRL33MHAKXQLA1 support in-circuit debugging?
Yes - it supports on-chip debugging via Infineon's DAS (Debug Access Service) interface using the OCDS (On-Chip Debug Support) protocol. This enables real-time register inspection, breakpoint setting, and flash programming through JTAG-compatible emulators like Lauterbach TRACE32 or Hitex C166 development tools.
What is the maximum operating temperature range for this part?
C167CRL33MHAKXQLA1 is rated for industrial temperature operation from –40 °C to +85 °C, verified per Infineon's qualification standards for MQFP-144 packages. Thermal derating begins above 70 °C ambient when operating at full 33 MHz with sustained peripheral activity.
Can the on-chip PLL be bypassed to use an external clock source directly?
Yes - the PLL can be disabled via the PLLCON register, allowing direct use of an external clock applied to XTAL1 (with XTAL2 left unconnected or grounded). In bypass mode, maximum input frequency is 33 MHz, matching the rated CPU clock speed without multiplication.
Is there hardware support for EEPROM emulation in the on-chip RAM?
No - the device contains no dedicated EEPROM emulation hardware or wear-leveling logic. However, the 2 KB XRAM and IRAM can be used for software-based EEPROM emulation with external backup power or battery-backed SRAM, subject to endurance limits of standard CMOS RAM.
