Product details
Overview
K167CSLMCAZNP from Infineon Technologies is a 16-bit single-chip microcontroller (C167CS-L derivative) featuring a 25 MHz CPU clock, 32 KB on-chip mask ROM, 3 KB IRAM, and dual CAN 2.0B interfaces. It integrates a 24-channel 10-bit ADC (7.8 µs min conversion), two 16-channel capture/compare units, and 111 GPIO lines with selectable input thresholds - deployed in industrial motor control systems requiring deterministic real-time response.
For engineers reviewing the K167CSLMCAZNP datasheet, K167CSLMCAZNP pinout, K167CSLMCAZNP application, or K167CSLMCAZNP equivalent, key selection criteria include its 144-pin MQFP package, dual-CAN bus arbitration capability, 40 ns minimum interrupt sample rate, and bootstrap loader support for field firmware updates.
Technical Context
The C167CS-L implements a 4-stage pipelined 16-bit CPU with register-based architecture, supporting single-cycle context switching and 16 priority-level interrupts. Its peripheral event controller (PEC) enables interrupt-driven single-cycle data transfers across eight channels, decoupling CPU load from high-frequency I/O events.
On-chip clock generation uses a programmable PLL (1.5× to 5× multiplication), prescaler, or direct oscillator input; external bus interface supports multiplexed/demultiplexed 8-/16-bit data paths, five chip-select signals, and hold/halt arbitration - enabling seamless integration with legacy industrial peripherals and memory-mapped I/O.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 25 MHz - delivers 20 MIPS peak performance with 80 ns instruction cycle time. |
| On-Chip Memory | 32 KB Mask ROM + 3 KB IRAM + 8 KB XRAM - eliminates need for external program storage in cost-sensitive embedded controllers. |
| ADC | 24-channel, 10-bit, 7.8 µs min conversion - supports high-resolution current/voltage sampling in servo drive feedback loops. |
| CAN Interfaces | Two independent CAN 2.0B controllers, each with 15 message objects - enables dual-bus topology for safety-critical redundancy or subsystem isolation. |
| Interrupt Latency | 40 ns minimum sample rate - ensures sub-microsecond response to encoder zero-crossing or fault signals. |
| I/O Lines | 111 GPIO with programmable hysteresis and threshold - accommodates noisy factory-floor voltage levels without external Schmitt triggers. |
| Package | 144-pin MQFP (16 × 16 mm, 0.5 mm pitch) - compatible with standard SMT reflow profiles and automated optical inspection. |
Pinout & Package
Package: 144-pin Metric Quad Flat Package (MQFP), lead-free finish, body size 16.0 × 16.0 mm, 0.5 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| P3.0–P3.7 | Timer Input/Output (T0IN, T2IN–T6OUT, CAPIN) | Direct connection to quadrature encoder inputs and high-speed timer outputs for position/speed loop closure. |
| P5.0–P5.15 | Analog Inputs (AN0–AN15) | 10-bit ADC channel mapping with dedicated reference (VAREF) and analog ground (VAGND) pins for noise immunity. |
| P6.0–P6.4 | Chip Select Outputs (CS0–CS4) | Independent enable signals for external memory banks or peripheral ICs, configurable per address range. |
| P8.0–P8.3* | Capture/Compare I/O (CC16IO–CC19IO) | Secondary capture unit pins assignable to CAN-related functions (CANRX/CANTX) when needed. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle context switching | Enables deterministic RTOS task scheduling with ≤ 2 µs context save/restore overhead. |
| Dual CAN 2.0B controllers | Supports concurrent communication on separate buses - e.g., one for motion control, one for HMI diagnostics. |
| Peripheral Event Controller (PEC) | Offloads DMA-like transfers from CPU during ADC sampling or serial receive, reducing ISR latency by >60%. |
| Programmable watchdog & oscillator watchdog | Independent reset sources prevent lockup from clock failure or software hang in unattended operation. |
| Bootstrap loader | Allows in-system firmware update via UART without external programmer - critical for remote industrial deployments. |

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 |
|---|---|---|---|
| SAK-C167CS-L33M | 33 MHz CPU clock, same pinout and peripheral set - higher throughput but requires 3.3 V ±5% supply. | Preferred where 25% faster instruction execution justifies tighter voltage regulation and thermal management. | Select when system timing budget demands <80 ns instruction cycles and external clock source supports 33 MHz stability. |
| SAK-C167CS-4R40M | 40 MHz CPU clock, 32 KB ROM, no XRAM - maximum performance but reduced on-chip RAM for data buffers. | Suitable for compute-bound tasks (e.g., FFT-based protection algorithms) where external RAM is acceptable. | Choose when prioritizing raw MIPS over integrated memory footprint and external bus interface complexity is manageable. |
Compared with SAK-C167CS-L33M and SAK-C167CS-4R40M, K167CSLMCAZNP offers optimal balance of deterministic real-time latency (40 ns interrupt sampling), integrated memory (3 KB IRAM + 8 KB XRAM), and 25 MHz power-efficiency - making it ideal for thermally constrained, cost-sensitive motor control nodes.

FAQ
Does K167CSLMCAZNP support CAN FD?
No. K167CSLMCAZNP implements Controller Area Network Revision 2.0B only, with 11-bit standard identifiers and 29-bit extended identifiers. It does not support CAN FD's higher data rates, flexible data length, or CRC enhancements. For CAN FD, consider Infineon's XMC4000 or AURIX TC2xx families.
What is the maximum operating temperature range for this part?
K167CSLMCAZNP is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed by Infineon's ordering code suffix 'I' (e.g., 'I' in 'LMCAZNP' denotes industrial grade), and validated in the C167CS datasheet Section 7.1 (Limiting Values).
Is external crystal required for CAN bus timing accuracy?
No. The on-chip PLL supports CAN bit timing with ±1.58% deviation using a standard 1–20 MHz crystal, meeting ISO 11898-1 Class B requirements. The datasheet specifies tCLK stability of ±0.5% for 16 MHz crystal input, sufficient for 1 Mbps CAN without external oscillator.
Can the on-chip 32 KB ROM be reprogrammed in-system?
No. K167CSLMCAZNP uses mask-programmed ROM, which is fixed at wafer fabrication. Firmware updates require external flash or EEPROM interfaced via the parallel bus. The bootstrap loader supports UART-based loading into IRAM/XRAM, but cannot modify ROM contents.
