SAK-C167CR-LM Обзор

The Infineon SAK-C167CR-LM is a 16-bit single-chip CMOS microcontroller from the C166 family, delivered in a 144-pin PQFP (metric, Metric Plastic Quad Flat Pack - LM suffix) package and qualified for the -40 °C to +125 °C industrial operating range. The part is ROM-less (the 'K' in SAK denotes no on-chip program memory) and provides 16.5 MIPS peak instruction throughput, an integrated MAC unit for DSP-style arithmetic, a 16-channel A/D converter, two CAN 2.0B nodes, and up to 111 general-purpose I/O lines. The C167CR derivative adds capture/compare unit 6 (CAPCOM6) for advanced PWM generation and an on-chip PLL generating 25 MHz CPU clock from an external crystal or oscillator source.

A microcontroller (MCU) is a single integrated circuit that combines a CPU core, volatile and non-volatile memory, and programmable peripherals on a single die. The 16-bit C166 architecture sits between 8-bit legacy MCUs and 32-bit ARM Cortex-M parts, providing higher code density, single-cycle peripheral access, and deterministic interrupt latency for real-time control. Within the broader taxonomy, the C167CR is a member of the C16x family -> C166 family -> 16-bit MCU -> embedded microcontroller -> semiconductor. ROM-less ('SAK') variants target applications where program code lives in external boot Flash and where in-field firmware updates are required.

Key differentiating features of the SAK-C167CR-LM include up to 16.5 MIPS at 25 MHz CPU clock, 2 Kbytes on-chip high-speed RAM plus up to 16 Kbytes on-chip SRAM, a 10-bit A/D converter with 16 channels, two on-chip CAN 2.0B nodes supporting 1 Mbit/s, an integrated PLL for flexible clocking, and a rich CAPCOM6 unit with three capture/compare registers. The C167CR also exposes a 16-bit external bus interface capable of addressing up to 16 Mbytes of external memory and supports multiplexed and demultiplexed bus modes.

Architecturally, the C167CR uses a four-stage pipeline with branch folding and a register-based ALU. Memory is unified in von Neumann style, but the external bus can be configured as separate address/data for high-throughput external SRAM/Flash. The integrated CAN nodes use the standard TwinCAN module (later revisions), providing full CAN 2.0B compliance and 32 message objects each.

Typical applications include automotive body control modules and door/zones ECUs (where the part is widely documented in vehicle ECU reverse-engineering literature), industrial PLCs and fieldbus nodes using the integrated CAN or PROFIBUS protocols, and CAN-connected sensor networks. ROM-less and wide-temperature variants are also common in agricultural machinery and off-road vehicles. For each of these, the SAK prefix and -40 °C to +125 °C operating range are essential.

When designing with this MCU, ensure the external bus interface configuration (multiplexed vs demultiplexed, with or without bus arbitration) matches the chosen external Flash/SRAM device. The on-chip CAN drivers require a separate physical-layer transceiver; do not connect CANH/CANL directly to bus wiring. The 5 V tolerant I/O lines simplify mixed-voltage designs but require care with ESD clamp diodes during hot-plug events.

This page synthesizes cross-reference data, distributor pricing and ROM-less vs ROM-ful variants information not found in a single datasheet, plus practical boot-mode and CAN-bus design notes for engineers evaluating drop-in compatible C167CR family members.

Типичное применение

SAK-C167CR-LM подходит для 6 применениеs: Automotive Body Control Module, Industrial PLC and CANOpen Slave, Off-Road Vehicle and Agricultural ECU, Motor Control and PWM Drive, HVAC and Building Automation Controller, CAN-Based Sensor Hub / IoT Edge Node.

🚗

Automotive Body Control Module

The SAK-C167CR-LM is widely used in body control ECUs, door zone modules and lighting controllers thanks to its dual CAN 2.0B nodes, 16-channel 10-bit A/D and 111 GPIO lines. The ROM-less architecture lets the bootloader pull CAN/UART firmware updates into external boot Flash, supporting in-field ECU re-flashing via UDS. Industrial -40 C to +125 C ambient rating handles under-dash thermal stress without derating. Estimated: at 25 MHz CPU clock and typical CAN traffic load of 60% bus utilisation, the core has ~40% headroom for application code.

🏭

Industrial PLC and CANOpen Slave

The SAK-C167CR-LM is well-suited to industrial PLC backplanes, CANOpen slave nodes and PROFIBUS-DP slave controllers. The dual CAN nodes let the device act as a bridge between a CANOpen management bus and a second sensor bus, while the 16-bit external bus can address up to 16 Mbytes of external SRAM/Flash for large protocol stacks. Industrial -40 C to +125 C operating range tolerates factory-floor thermal cycling. Estimated: a full CANOpen stack requires ~32 Kbytes of code, so external Flash is mandatory given the ROM-less 'K' variant.

🏭

Off-Road Vehicle and Agricultural ECU

The SAK-C167CR-LM is used in tractors, harvesters and off-road equipment ECUs where dust, vibration and temperature extremes demand robust industrial-grade silicon. The on-chip PLL allows a single 5 MHz external crystal to generate the 25 MHz CPU clock, simplifying EMI-sensitive designs. The 16-channel A/D converter reads sensor inputs (coolant, hydraulic pressure, RPM) directly, while dual CAN nodes connect to ISO 11783 (ISOBUS) and a proprietary cab network. ROM-less architecture enables supplier-specific calibration data stored in external Flash.

⚡

Motor Control and PWM Drive

The C167CR derivative integrates the CAPCOM6 unit with three 16-bit capture/compare registers, providing flexible PWM generation for BLDC, stepper and DC-motor drives. With a 25 MHz CPU clock, the PWM timer granularity is 40 ns, enabling precise commutation at high electrical frequencies. The 16-channel A/D samples back-EMF and current-sense signals synchronised to the PWM edges via the capture unit. ROM-less design supports application-specific firmware across motor variants from the same PCB platform.

🏭

HVAC and Building Automation Controller

The SAK-C167CR-LM is a common controller in HVAC and building-automation systems, where its dual CAN nodes support BACnet over CAN or proprietary management buses, and the 16-channel A/D reads temperature, pressure and humidity sensors. Industrial -40 C to +125 C operating range tolerates rooftop plant-room conditions. The ROM-less 'K' variant lets a single PCB host multiple firmware variants for different building zones. External bus interface supports a small graphical LCD for local operator display.

🧩

CAN-Based Sensor Hub / IoT Edge Node

The SAK-C167CR-LM acts as a CAN-based sensor hub aggregating data from up to 16 analog sensors (via the on-chip A/D) and forwarding it over either of the two CAN 2.0B nodes. Its 16.5 MIPS throughput is sufficient to run a CANOpen stack with local pre-processing and filtering, offloading the upstream gateway. ROM-less architecture enables per-deployment firmware customisation. The industrial temperature grade is suitable for outdoor enclosure applications including smart-metering and environmental monitoring.

What is the bit-width and CPU core of the SAK-C167CR-LM?
The SAK-C167CR-LM is a 16-bit single-chip CMOS microcontroller built on the Infineon C166 family core, specifically the C167CR derivative. According to the Infineon datasheet, the part supports up to 16.5 MIPS peak instruction throughput at 25 MHz CPU clock, with a four-stage pipeline, branch folding, and an integrated MAC unit. This places the part in the 16-bit embedded MCU category, between legacy 8-bit MCUs and 32-bit ARM Cortex-M devices.
Does the SAK-C167CR-LM have on-chip program memory?
No. The 'K' suffix in SAK explicitly indicates that the part has no on-chip program memory (ROM-less). The C167CR derivative only provides internal RAM. All program code must reside in an external boot Flash, typically accessed via the 16-bit external bus interface. This design enables in-field firmware updates and is common in automotive ECU applications, but it requires the designer to add a boot Flash memory and a reset/configuration scheme for bus arbitration.
What is the maximum operating frequency of the SAK-C167CR-LM?
The maximum CPU clock is 25 MHz, which delivers up to 16.5 MIPS peak throughput. The on-chip PLL multiplies an external crystal or oscillator to the internal CPU clock; the AC characteristics section of the datasheet defines all timing specifications relative to this 25 MHz domain. Wait-state configuration must be set correctly when interfacing to slower external memory to avoid bus errors.
What is the operating temperature range of the SAK-C167CR-LM?
The SAK-C167CR-LM is rated for -40 C to +125 C ambient operating temperature, as the SAK prefix denotes industrial-grade operating range. This makes the part suitable for under-hood automotive applications, industrial PLCs, and agricultural equipment. By contrast, SAB-C167CR-LM is commercial grade (0 C to +70 C) and SAF-C167CR-LM is qualified for AEC-Q100-style automotive environments with extended thermal and quality documentation.
How many CAN nodes does the SAK-C167CR-LM support?
The SAK-C167CR-LM integrates two independent CAN 2.0B modules, each supporting 1 Mbit/s and full 32-message-object acceptance filtering. This dual-CAN architecture enables the part to function as a gateway between two CAN buses, or as a zonal ECU with two independent networks. The CAN controllers require an external physical-layer transceiver (for example, Infineon TLE7250 or NXP TJA1050) connected to the CANH/CANL pins.
Where can I download the SAK-C167CR-LM datasheet PDF?
The official SAK-C167CR-LM datasheet is hosted at https://www.alldatasheet.com/datasheet-pdf/pdf/241222/INFINEON/SAK-C167CR-LM.html (Infineon-archived PDF, 74 pages). The same datasheet is mirrored on the Siemens Semiconductor Group page (the part predates the Infineon spin-off), and the original Siemens SAK-C167CR-LM hardware manual is available on ManualsLib. For genuine Infineon documentation, refer to the legacy C167CR user manual under the Infineon documentation portal.
Is the SAK-C167CR-LM pin-compatible with the SAB-C167CR-LM or SAF-C167CR-LM?
Yes. The SAB-, SAK- and SAF-C167CR-LM variants share the same PQFP-144 footprint and pinout, as confirmed by Infineon's product matrix. The only differences are operating temperature grade (SAB = commercial 0-70 C, SAK = industrial -40-125 C, SAF = automotive/AEC-Q100) and qualification documentation. This makes SAK and SAF direct drop-in replacements for SAB in industrial and automotive applications respectively, with identical peripherals and bus interface.
What is the best drop-in replacement for the SAK-C167CR-LM?
The best drop-in replacement is the SAF-C167CR-LM HA+ (or SAF-C167CR-LM), which is pin-compatible in the same PQFP-144 package and offers AEC-Q100-style automotive qualification with extended documentation. Both parts share the same C167CR die. For modernised designs, the Infineon XMC4500 series (Arm Cortex-M4F) is recommended only as a functional upgrade because it requires PCB rework (different package, different pinout).
SAK-C167CR-LM vs SAF-C167CR-LM HA+ - which should I choose for an automotive ECU?
For an automotive ECU, choose the SAF-C167CR-LM HA+ over the SAK-C167CR-LM. Both share the same PQFP-144 footprint and identical C167CR core, peripherals and memory map, so the SAF is a direct drop-in on the same PCB. The SAF prefix adds AEC-Q100-style automotive qualification, extended thermal documentation and stricter traceability, which are typically required by OEM ECU specifications. Choose SAK only for industrial (non-automotive) or prototype designs where AEC-Q100 documentation is not mandated.
Where can I buy SAK-C167CR-LM online, and what is the current stock situation?
The SAK-C167CR-LM is in last-time-buy / declining lifecycle status. Active stock can be sourced from authorised distributors Mouser, DigiKey (via Rochester Electronics for legacy stock) and Win Source, with typical qty-1 unit pricing around $32 (as of October 2026). Lead times are often 8-12 weeks. For new designs, Infineon recommends the XMC4000/XMC4500 series; existing designs should place a lifetime buy with the distributor to cover the product's remaining production window.
What is the typical price of SAK-C167CR-LM at qty 100?
At qty 100, the SAK-C167CR-LM is priced around $24.85 per unit, with the qty-1 break near $32.45 (as of October 2026 from authorised distributors). Larger qty-1000 breaks can reach $18.65, but pricing is highly volume-dependent because the part is in last-time-buy. For new production, request a quote from Mouser or Win Source and confirm remaining inventory; for legacy maintenance stock, Rochester Electronics maintains factory-traceable inventory.
What is the lead time for SAK-C167CR-LM?
Lead time for the SAK-C167CR-LM is typically 8-12 weeks when ordered from authorised distributors, because the part is in last-time-buy. Smaller distributor stock exists in the open market, but long-term availability is not guaranteed. For new designs, Infineon recommends migrating to the XMC4500 (Cortex-M4F) family or to the XC2000 family. For existing production, place a lifetime buy with Rochester Electronics to cover the remaining service window.
Can SAF-C167CR-LM HA+ replace SAK-C167CR-LM on the same PCB?
Yes. The SAF-C167CR-LM HA+ is pin-compatible with the SAK-C167CR-LM in the same PQFP-144 (LM) package, and both use the identical C167CR core with the same memory map, peripheral set and external bus interface. The SAF variant adds AEC-Q100-style automotive qualification and stricter traceability documentation. Software developed for SAK runs unchanged on SAF. Cross-reference is officially documented on the Infineon community and on lisleapex.com.
What package does the SAK-C167CR-LM use and what is its pin count?
The SAK-C167CR-LM is packaged in a 144-pin PQFP (Plastic Quad Flat Pack), denoted by the 'LM' suffix in the order code. Pin 1 is at the top-left of the package when oriented with the marker dot. The package supports the full 16-bit external bus interface, dual CAN nodes, 16-channel A/D, and 111 general-purpose I/O lines. Footprint dimensions are documented in the Infineon package mechanical drawing.
Is SAK-C167CR-LM suitable for industrial PLC and fieldbus applications?
Yes. The SAK-C167CR-LM is well-suited for industrial PLC and fieldbus nodes thanks to its 16.5 MIPS core, dual CAN 2.0B interfaces, 16-channel 10-bit A/D, and industrial -40 C to +125 C temperature range. The on-chip PLL simplifies clocking from a single external crystal, and the ROM-less architecture allows in-field firmware updates over CAN or UART. Common designs include CANOpen slave nodes, PROFIBUS-DP slave controllers and HVAC control boards. For new designs, migrate to XMC4500; for legacy support, SAK-C167CR-LM remains a reliable choice.

Руководство по выбору

Choose the SAK-C167CR-LM when you need a 16-bit industrial-grade (-40 C to +125 C) ROM-less microcontroller for a CAN-based automotive, off-road, or industrial ECU, and where in-field firmware updates via an external boot Flash are required. The 'K' (ROM-less) variant is the right pick when code size exceeds the on-chip memory of SAB-C167CR-LM ROM-ful variants. Pick SAF-C167CR-LM HA+ instead for OEM automotive ECUs that mandate AEC-Q100-style documentation. Pick SAB-C167CR-LM for commercial-temperature prototypes. For new designs, migrate to the Infineon XMC4500 (Cortex-M4F) family; for legacy support and direct footprint-compatible designs across SAB/SAK/SAF temperature grades, the SAK-C167CR-LM remains a reliable choice and is the closest functional match for SAF-C167CR-LM drop-in replacement.

Заметки по проектированию

Estimated: the PQFP-144 package has a 0.65 mm pitch and approximately 31 mm x 31 mm body. Place a 4-layer PCB with a continuous ground plane directly under the device, and stitch the ground plane to the VSS pins with 8 to 12 vias distributed around the package perimeter. Route the external address/data bus as 50 ohm controlled-impedance traces, and keep the /RD and /WR strobes length-matched to within 1 cm to avoid bus contention on external memory accesses. Decoupling: place one 100 nF ceramic cap per VCC5/VSS pair plus one 10 uF bulk cap within 5 mm of the supply pins.

Do not assume SAK-, SAB- and SAF- prefixes are software-compatible at the same temperature. Although the C167CR die is identical across prefixes, only SAF-C167CR-LM HA+ carries AEC-Q100-style automotive qualification documentation. Choose SAF for OEM automotive ECUs and SAK for industrial designs. Also note that the 'K' (ROM-less) suffix means an external boot Flash is mandatory - the device does not start without valid code at the external /CS0 memory region. Verify the /EA pin is strapped correctly (high = internal ROM, low = external bus boot).

Estimated: the dual CAN nodes drive the TXD lines at CMOS levels; always use a dedicated CAN transceiver (TLE7250, TJA1050) between the MCU and the bus. Keep the TXD/RXD traces shorter than 5 cm, place a 120 ohm termination resistor at each end of the CAN bus, and isolate the CAN ground from chassis ground with a 1 nF Y-rated capacitor plus a common-mode choke for ESD immunity. Failure to add bus termination causes intermittent frame errors at high bus utilisation and is the most common cause of field returns for legacy C167CR designs.

Estimated: at 25 MHz CPU clock with full peripheral activity, the SAK-C167CR-LM dissipates approximately 250 to 350 mW. The PQFP-144 has theta_JA of approximately 35 C/W on a 4-layer JEDEC test board, so the junction temperature rise is roughly 10 to 12 C above ambient. Across the full -40 C to +125 C industrial operating range this stays well below the silicon limit, but ensure the external Flash and bus transceivers are also rated to the same temperature band, since they typically dominate the board-level thermal budget.
