Product details
Overview
C167SRLMHABXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller with 2 kB on-chip XRAM, 25 MHz CPU clock, CAN 2.0B interface, and 10-bit 16-channel A/D converter. It integrates dual CAPCOM units, 4-channel PWM, two general-purpose timers, and supports external memory expansion up to 16 Mbytes. Used in industrial motor control systems requiring real-time I/O handling and deterministic communication.
For engineers reviewing the C167SRLMHABXUMA1 datasheet, C167SRLMHABXUMA1 pinout, C167SRLMHABXUMA1 application, or C167SRLMHABXUMA1 equivalent, key selection criteria include CAN protocol compliance, 10-bit ADC resolution with 7.8 µs minimum conversion time, PLL-based clock generation (1.5×–5× multiplication), and support for idle/power-down modes in embedded control environments.
Technical Context
The C167SRLMHABXUMA1 implements a 4-stage pipelined 16-bit CPU with register-based architecture, single-cycle context switching, and 16 Mbyte linear address space. Its interrupt system delivers 56 sources across 16 priority levels with sample rates down to 40 ns, coordinated via a Peripheral Event Controller for single-cycle data transfers.
On-chip peripherals include a full-CAN module with 15 message objects, two synchronous/asynchronous serial channels, and an oscillator watchdog for clock failure detection. Memory mapping supports mask ROM variants (0/32/128 kB), while external bus timing is programmable per address range with hold/hold-acknowledge arbitration.

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 |
|---|---|---|---|
| C167CR-LM | Same package and pinout; includes 32 kB mask ROM instead of zero ROM | Boot firmware stored on-chip; eliminates external boot ROM requirement | Select when fixed application code must reside internally and ROM reprogramming is unnecessary |
| C167SR-L33M | Identical feature set but rated for 33 MHz CPU clock (vs. 25 MHz) | Higher throughput for compute-intensive tasks; requires tighter timing margins on external bus | Select when deterministic sub-µs response latency is required and board layout supports 33 MHz stability |
Compared with C167CR-LM, C167SRLMHABXUMA1 trades on-chip ROM for flexibility in field-upgradable firmware; compared with C167SR-L33M, it offers lower power consumption and relaxed timing constraints at the cost of peak performance.

FAQ
Does C167SRLMHABXUMA1 include on-chip flash or ROM memory?
No. This variant contains 2 kB of on-chip XRAM and 2 kB of IRAM but no mask ROM or flash memory. Boot code must be loaded externally via the bootstrap loader through serial channel or external memory interface.
What is the maximum operating temperature range for C167SRLMHABXUMA1?
The device is specified for industrial temperature range: –40 °C to +85 °C ambient, validated per Infineon's qualification standards for MQFP-144 packaging and 0.5 µm process technology.
Can C167SRLMHABXUMA1 directly drive a CAN bus without external transceiver?
No. It provides only the CAN protocol controller (CANRX/CANTX signals); an external physical-layer transceiver (e.g., TJA1040 or PCA82C251) is required to meet ISO 11898-2 electrical specifications.
Is the PLL capable of generating clocks for both CPU and peripheral subsystems independently?
No. The on-chip PLL generates a single system clock; peripheral clocks (e.g., for ADC, timers, serial channels) are derived via prescalers from this master clock, with individual enable/disable control but no independent frequency synthesis.
