SAB-C167CS-L40M - 40MHz 16-bit C167CS MCU ROM-less | Infineon
MPN: SAB-C167CS-L40M ⚠ Waktu Beli TerakhirSAB-C167CS-L40M Ringkasan
A 16-bit single-chip microcontroller (MCU) is an integrated processor core, memory, and peripheral set on a single die, executing instructions from on-chip or external program memory and serving as the central controller for embedded systems. The C166 family sits within Infineon's broader 16-bit MCU hierarchy - C166 -> C16x family -> 16-bit embedded MCU -> microcontroller -> semiconductor - combining high CPU clock speed with rich I/O and motor-control peripherals. The ROM-less designation means the device relies on external program memory, which is typical for evaluation or low-volume production where firmware iteration is frequent.
Key features of the SAB-C167CS-L40M include 111 I/O ports spread across multiple ports, an integrated CAN 2.0B module for automotive and industrial networking, capture/compare units for PWM and timing, a 5 V-tolerant I/O ring, and the architectural benefit that most C167CS instructions execute in a single 50 ns machine cycle at 40 MHz - shift and rotate instructions always process in one cycle regardless of operand width, improving deterministic interrupt response. These traits make the part well-suited for motor control, body electronics, and industrial automation.
Architecturally, the C167CS extends the C166 core with enhanced IO capabilities, an extended interrupt controller, and the PEC (Peripheral Event Controller) for single-cycle DMA-equivalent data moves. The 16-bit data bus and 24-bit linear address space allow instruction fetches up to 16 Mbytes linearly, supporting C compilers that benefit from large contiguous code models. Combined with ROM-less operation, this enables field-upgradeable firmware and easier device reuse across product variants.
Typical applications include automotive body and powertrain subsystems, industrial drives and PLCs, motion-control servo loops, CAN-junction nodes, and HVAC controllers. Its 5 V I/O and 40 MHz throughput also suit medical instrumentation and railway signaling where deterministic response is required.
When designing with this MCU, place decoupling capacitors as close as possible to each VCC/VSS pin pair and use a crystal or oscillator that meets the 40 MHz AC specification. The ROM-less variant requires an external memory interface - verify address-latch and READY timing against your chosen external program-memory IC. Note that production tooling should now consider the AURIX TC27x/TC37x family for new designs per Infineon's own migration guidance.

Aplikasi Umum
SAB-C167CS-L40M cocok untuk 6 aplikasis: Automotive Body Electronics, Industrial Drives & Servo Loops, CAN-Junction / Gateway Nodes, HVAC Control Systems, Medical Instrumentation Front-End, Motion-Control / Robotic Servo Nodes.
Automotive Body Electronics
The SAB-C167CS-L40M is well suited to automotive body-electronics modules (BCM, lighting controllers, door/roof modules) because of its integrated CAN 2.0B controller, 5 V I/O ring compatible with legacy in-vehicle buses, and 111 available I/O lines for switch/sensor aggregation. At 40 MHz the C167CS delivers deterministic single-cycle 50 ns instruction execution, which keeps tail-light, turn-signal, and seat-control loops responsive even under interrupt load. Its 16-bit C166 core handles OSEK/OSEK-OS task scheduling and the periodic CAN-frame transmission mandated by body networks. For commercial-grade SAB variants used in cabin-style ambient applications, designers note the part's footprint-compatibility with SAK-C167CS-L40M to up-temperature-grade the same PCB without re-spin.

Industrial Drives & Servo Loops
For industrial variable-frequency drives, stepper/servo controllers, and PLC scan engines, the SAB-C167CS-L40M provides the 16-bit fixed-point arithmetic and capture/compare PWM channels needed for closed-loop motor control. Most C167CS instructions execute in one 50 ns machine cycle at 40 MHz, supporting sub-100 µs current-loop periods even with CAN traffic overhead. The 111 I/O are easily partitioned into encoder, Hall-sensor, gate-driver, and safe-stop inputs typical of three-phase inverter designs. ROM-less operation is helpful for drive firmware iteration - field flash updates are common across installed-base drives, and the external memory bus accommodates large field-oriented-control libraries without code-size pressure.

CAN-Junction / Gateway Nodes
The on-chip CAN 2.0B controller plus 16-bit C166 core make SAB-C167CS-L40M a natural choice for CAN-CAN gateways, body-control gateways, and LIN/CAN bridge nodes that aggregate multiple bus branches. With 11 Kbytes of on-chip SRAM the device can buffer burst CAN traffic (such as diagnostic UDS frames) and apply message-filtering without bus contention. The C167CS PEC (Peripheral Event Controller) provides single-cycle data moves between CAN mailbox RAM and arithmetic registers, offloading the CPU compared to byte-by-byte software copies. Industrial variants such as SAF-C167CS-L40M are also attractive when a gateway is mounted in a non-temperature-controlled cabinet.

HVAC Control Systems
HVAC controllers for commercial buildings and industrial enclosures benefit from the SAB-C167CS-L40M's 5 V analog front-end tolerance, generous I/O count (111 lines for thermistor inputs, fan PWM, valve triac control), and real-time interrupt determinism. Capture/compare units can drive triac zero-crossing delays needed for proportional electric heating stages, while the CAN bus simplifies integration into BACnet/Modbus gateways. ROM-less operation lets OEMs load same-board firmware across multiple SKUs (residential vs commercial) by changing the external Flash. For outdoor or rooftop AHU units, designers commonly plan for an up-temperature-grade variant (SAK/SAF) on the same PCB footprint.

Medical Instrumentation Front-End
The SAB-C167CS-L40M is used as the system controller in mid-complexity medical instrumentation - patient monitors, infusion pumps, bench-top analyzers - where 16-bit fixed-point throughput, deterministic interrupt response, and a 5 V analog-friendly I/O ring simplify the signal-conditioning chain. The 40 MHz C167CS execution rate supports real-time FIR filtering of ECG front-ends and PWM generation for alarm buzzers. Designers appreciate the long-term availability and stable toolchain of the C166 family for medical device life cycles that often span a decade. Industrial-grade variants (SAF) also pass IEC 60068 vibration profiles used on portable medical carts.
Direkomendasikan
Motion-Control / Robotic Servo Nodes
Multi-axis motion controllers and robotic servo nodes leverage the SAB-C167CS-L40M's capture/compare PWM channels (typically 4-8 channels), 40 MHz instruction throughput, and 111 I/O for end-of-travel, encoder-index, and emergency-stop signal aggregation. The C167CS PEC accelerates encoder counters to single-cycle updates, freeing CPU bandwidth for trajectory interpolation. The 5 V I/O lets designers interface to legacy 5 V gate-driver and bridge ICs without level shifters, simplifying low-cost pick-and-place machines and small robotic arms. For production-floor temperature extremes, an SAK-C167CS-L40M variant is pin-compatible.

Diferensiator Kunci
- Same MQFP-144 footprint with automotive-grade silicon inside (pin-compatible temperature upgrade) (vsSAK-C167CS-L40M)
- Industrial-grade temperature tolerance at lower cost than full automotive grade (vsSAF-C167CS-L40M)

Catatan Desain
Place 100 nF X7R ceramic decoupling capacitors as close as possible to every VDD/VSS pin pair of the MQFP-144 (P-MQFP-144-8) package - the C167CS data sheet and Infineon application notes recommend one cap per supply pin, with an additional bulk 10 µF tantalum or 22 µF ceramic on each side of the package. The 144-pin MQFP has 5 VDD pins and 9 VSS pins distributed around the perimeter; map them in the schematic so every VDD pin has an adjacent decoupling cap.
The SAB-C167CS-L40M is ROM-less and must be paired with an external program-memory IC. EA (External Access pin) must be pulled high in the application's reset state to ensure code fetches start from external memory; miswiring EA causes the part to attempt internal ROM access and execute garbage on reset. Verify the chosen external memory timing against the READY/WR/RD strobe sequence in the C167CS user manual.
The external bus at 40 MHz (50 ns cycle) is sensitive to trace impedance. Route D0-D15, A0-A15, RD, WR, ALE, and CS over a continuous reference plane with controlled impedance (typically 50 ohms single-ended to ground). Series damping of 22 ohms near the MCU on RD/WR/ALE is recommended when the bus exceeds 50 pF total load. Add source termination if address lines are longer than 50 mm.
Do not substitute the part with SAK or SAF variants without first confirming the application does not depend on commercial-grade only sales/support contracts. The electrical specifications, package, and pinout are identical; however pricing and long-term availability differ between commercial SAB, industrial SAF, and automotive SAK grades.
