Product details
Overview
SAB-C167CR-16RM HA+ from Infineon Technologies is a 16-bit single-chip microcontroller with 128 KB on-chip mask ROM, 2 KB internal RAM, and 2 KB XRAM, operating at 25 MHz with a 4-stage pipeline CPU delivering 80 ns instruction cycle time. It integrates a CAN 2.0B interface, 16-channel 10-bit ADC (7.8 µs conversion), dual CAPCOM units, 4-channel PWM, and supports up to 111 GPIO lines with selectable input thresholds - deployed in industrial motor control and embedded automation systems.
For engineers reviewing the SAB-C167CR-16RM HA+ datasheet, SAB-C167CR-16RM HA+ pinout, SAB-C167CR-16RM HA+ application, or SAB-C167CR-16RM HA+ equivalent, key selection criteria include its 128 KB mask ROM capacity, P-MQFP-144-8 package compatibility, CAN 2.0B compliance, 25 MHz operation with PLL clock generation, and support for peripheral event controller (PEC)-driven DMA transfers.
Technical Context
The C167CR implements a register-based 16-bit CPU with hardware-supported context switching, enabling deterministic real-time interrupt response down to 40 ns sample rate across 56 interrupt sources. Its memory architecture provides unified 16 MB linear address space, with on-chip IRAM/XRAM co-located for low-latency peripheral access and external bus controller supporting multiplexed/demultiplexed 8/16-bit data buses.
Peripheral integration includes two independent serial channels (asynchronous/synchronous/HS-synchronous), dual 16-channel CAPCOM units for precise timing capture and waveform generation, and a dedicated CAN module with 15 message objects and full CAN/BASIC CAN mode support - all synchronized via a shared peripheral clock domain derived from the on-chip PLL.

Use Value: 111 GPIO lines support direct wiring to 32 discrete inputs and 16 outputs; CAN message objects preconfigured for priority-based diagnostics and motion commands. |
| Energy Metering Gateway | Building HVAC Controller |
|
Use Scenario: Substation-level energy aggregation node collecting meter data over RS-485 and forwarding via CAN to SCADA network. IC Role / Device Role / Timing Role: Protocol bridge with dual serial channels (one RS-485, one CAN), performing CRC validation, timestamping, and buffer management. Use Value: Dual serial interfaces operate concurrently at independent baud rates; 2 KB XRAM buffers 256 kByte of meter logs before CAN transmission burst. |
Use Scenario: Zone-level HVAC controller regulating chillers, VAV boxes, and CO₂ sensors in commercial buildings. IC Role / Device Role / Timing Role: Real-time environmental regulator using 10-bit ADC for temperature/humidity, PWM for actuator control, and CAN for BACnet/IP gateway communication. Use Value: Programmable input thresholds on Port 6 tolerate ±10% supply variation from building power; watchdog timers enforce 500 ms fail-safe shutdown on sensor timeout. |
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-4RM | 32 KB mask ROM, same 2 KB RAM, 25 MHz, identical P-MQFP-144-8 package | Limited firmware storage; suitable for simpler control loops without lookup tables or multi-language UI assets | Select when firmware size ≤32 KB and cost sensitivity outweighs future upgrade headroom |
| SAB-C167CR-16R33M | Same 128 KB ROM and RAM, but rated for 33 MHz operation (1.32× CPU throughput) | Enables higher servo loop bandwidth and faster CAN message throughput (up to 1 Mbps with tighter timing margins) | Choose for new designs requiring >25 MHz deterministic timing or legacy board reuse with upgraded clock tree |
Compared with SAB-C167CR-4RM, the -16RM offers 4× ROM capacity for complex algorithms and calibration data; versus the -16R33M, it trades 33 MHz performance for validated 25 MHz stability in thermally constrained enclosures - both share identical peripheral sets and pinout.

FAQ
What is the maximum operating temperature range for SAB-C167CR-16RM HA+?
The SAB-C167CR-16RM HA+ is specified for industrial temperature operation from –40 °C to +85 °C. This rating is confirmed in Section 2.2 of the V3.3 datasheet under "General Device Information", and applies to the P-MQFP-144-8 package variant with HA+ suffix indicating extended temperature grade compliance.
Does this microcontroller support in-system programming (ISP)?
No - the SAB-C167CR-16RM HA+ uses mask-programmed ROM, not flash or EEPROM. Firmware is permanently written during wafer fabrication. Programming occurs only once, prior to device shipment. The on-chip bootstrap loader supports serial download into RAM only, not ROM reprogramming.
Can the CAN module operate at 1 Mbps according to ISO 11898-2?
Yes - the integrated CAN 2.0B controller supports bit rates up to 1 Mbps when paired with an external high-speed CAN transceiver (e.g., Infineon TLE6250). The module meets ISO 11898-1 protocol requirements; physical layer compliance depends on external transceiver selection and PCB layout per Section 3.10 of the datasheet.
Is there hardware support for floating-point arithmetic?
No - the C167CR CPU lacks dedicated floating-point instructions or hardware accelerator. All floating-point operations must be performed in software using ANSI C libraries or optimized fixed-point approximations. The 16×16 multiply (400 ns) and 32/16 divide (800 ns) units are integer-only, as documented in Section 1 "Summary of Features".
