Product details
Overview
MB95F636KNWQN-G-108-SNE1 from Cypress Semiconductor is an 8-bit microcontroller based on the F2MC-8FX CISC core, operating at up to 20 MHz with 64 KB flash memory and 4 KB RAM. It integrates LIN-UART, CAN 2.0B, and I²C interfaces, and supports 10-bit ADC (16 channels), PWM, and on-chip debug via single-pin interface. It targets automotive body electronics and industrial control systems requiring robust serial communication and low-pin-count integration.
For engineers reviewing the MB95F636KNWQN-G-108-SNE1 datasheet, MB95F636KNWQN-G-108-SNE1 pinout, MB95F636KNWQN-G-108-SNE1 application, or MB95F636KNWQN-G-108-SNE1 equivalent, key selection criteria include CAN/LIN coexistence, 1.8–5.5 V wide supply range, AEC-Q100 qualification, and single-wire on-chip debug capability for space-constrained automotive modules.
Technical Context
The MB95F636KNWQN-G-108-SNE1 implements the F2MC-8FX architecture with instruction-level compatibility across the 8FX family, enabling software reuse. It features a dedicated CAN controller supporting full CAN 2.0B protocol with message objects, FIFO buffering, and automatic retransmission - independent of CPU intervention.
LIN-UART operates in dual mode: as a standard UART or as a LIN 2.1/2.2-compliant transceiver with auto-baud detection, sync field generation, and checksum handling. The device uses a single external crystal (1–20 MHz) for both main and sub-clock domains, with internal PLL options for clock flexibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | F2MC-8FX 8-bit CISC, 20 MHz max - delivers >1.5× throughput vs legacy 8051 at same frequency |
| Flash Memory | 64 KB on-chip flash with EEPROM emulation - enables field firmware updates without external storage |
| RAM | 4 KB SRAM - sufficient for real-time CAN/LIN stack + application logic in compact nodes |
| Supply Voltage | 1.8 V to 5.5 V - supports direct connection to 3.3 V or 5 V automotive domains and brown-out resilience |
| CAN Interface | One CAN 2.0B controller with 32 message objects - handles concurrent TX/RX with hardware filtering and error confinement |
| LIN Interface | Dedicated LIN-UART supporting master/slave modes, auto-sync, and checksum per LIN 2.2 - eliminates need for external LIN transceiver in slave nodes |
| ADC | 10-bit SAR ADC with 16 input channels and scan mode - suitable for sensor monitoring (e.g., temperature, voltage, potentiometer) |
| Debug Interface | Single-pin on-chip debug (OCDS) - preserves I/O count while enabling full breakpoint and trace capability |
Pinout & Package
MB95F636KNWQN-G-108-SNE1 is housed in a 108-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), optimized for automotive PCB layouts with thermal pad and symmetric power/ground pin distribution.

| XTAL1/XTAL2 | Crystal oscillator inputs | Accepts 1–20 MHz fundamental-mode crystal; internal oscillator circuit eliminates need for external capacitors in many cases |
| VDD/VSS | Power supply pins | Multiple VDD/VSS pairs distributed across package corners - reduce IR drop and improve noise immunity in high-speed switching |
| OCDS | On-chip debug serial | Single-pin bidirectional debug interface - enables full SWD-like functionality using only one GPIO |
| RESET | Active-low reset input | Includes internal pull-up and glitch filter - ensures reliable reset assertion during power ramp and EMI events |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLGSP#V0 | RL78/G13 core, 32 MHz max, 64 KB flash, no integrated CAN - requires external CAN transceiver | Lacks native CAN; better suited for LIN-only or SPI-based sensor hubs where CAN is not required | Select when CAN is unnecessary and lower active power (92 μA/MHz) is prioritized over integration |
| MC9S08DZ60CLCR | S08 core, 40 MHz max, 60 KB flash, CAN 2.0A only - no LIN support; requires external LIN transceiver | Supports CAN but lacks LIN protocol engine - adds component count and layout complexity for LIN-based subsystems | Choose only if legacy S08 toolchain compatibility and CAN-only communication dominate design constraints |
Compared with R5F100PLGSP#V0 and MC9S08DZ60CLCR, MB95F636KNWQN-G-108-SNE1 uniquely combines CAN 2.0B and LIN 2.2 in a single AEC-Q100-qualified 8-bit MCU, reducing system-level BOM cost and enabling true dual-bus node autonomy without external transceivers.

FAQ
Is MB95F636KNWQN-G-108-SNE1 AEC-Q100 qualified?
Yes, MB95F636KNWQN-G-108-SNE1 is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C), with test reports covering HTOL, TCT, ESD, and AC/DC parametric validation. It meets automotive reliability standards for body electronics deployed outside the engine compartment.
Does this MCU support CAN FD?
No, MB95F636KNWQN-G-108-SNE1 implements CAN 2.0B only (up to 1 Mbps), not CAN FD. Its CAN controller lacks ISO 11898-1:2015 FD frame format support, payload extension, or flexible data-rate arbitration. For CAN FD, consider Cypress's FM4 or Traveo families.
What development tools are supported?
Cypress provides the F2MC-8FX Software Development Kit (SDK), FDT (Flash Development Toolkit), and the CY8CKIT-042-BLE development kit adapted for 8FX evaluation. On-chip debug uses the OCDS single-pin interface compatible with Cypress's MiniProg3 and third-party SWD adapters with OCDS firmware.
Can the LIN-UART operate simultaneously with CAN?
Yes, LIN-UART and CAN controllers operate independently with separate clock domains and interrupt vectors. Both peripherals can be active concurrently - for example, receiving LIN commands while transmitting CAN status frames - with no resource contention or shared register conflicts.
