Overview
M306N5FCTFP#UK from Renesas Electronics is a 16-bit flash-based microcontroller in the M16C/6N Group, built on high-performance silicon gate CMOS with the M16C/60 Series CPU core. It features 128 KB + 4 KB data flash memory, 5 KB RAM, one CAN 2.0B module, 10-bit A/D converter (26 channels), dual 8-bit D/A converters, and operates at up to 24 MHz (T-version: 20 MHz) across −40°C to +85°C. It targets automotive body control and industrial motor drive systems requiring real-time CAN communication and analog signal conditioning.
For engineers reviewing the M306N5FCTFP#UK datasheet, M306N5FCTFP#UK pinout, M306N5FCTFP#UK application, or M306N5FCTFP#UK equivalent, key selection considerations include its T-grade temperature rating (−40°C to +85°C), 100-pin QFP package (PRQP0100JB-A), integrated CAN 2.0B controller, 26-channel 10-bit ADC, and support for three-phase motor control via dedicated timer outputs and Z-phase input.
Technical Context
The M306N5FCTFP#UK implements the M16C/60 Series CPU core with 91 fundamental instructions and minimum instruction execution time of 50.0 ns at 20 MHz BCLK (T-version). Its architecture includes two register banks, 32-bit register pair support (R2R0, R3R1, A1A0), and hardware multiplier for accelerated arithmetic in motor control loops.
It integrates five peripheral domains: (1) CAN 2.0B module with message object buffers; (2) dual DMAC channels supporting memory-to-peripheral transfers; (3) CRC-CCITT calculation circuit for protocol integrity; (4) three serial interfaces - UART, clock-synchronous, I²C-bus (1 channel), and IEBus (2 channels); and (5) three-phase motor control circuit with TA0–TA4 timers, TB0–TB5 inputs, and U/V/W output pins.

FAQ
What is the operating temperature range for the M306N5FCTFP#UK?
The M306N5FCTFP#UK is the T-version of the M16C/6N5 MCU, rated for −40°C to +85°C ambient operation. This qualification aligns with automotive body electronics requirements and distinguishes it from the Normal-ver. (−40°C to +85°C, wider voltage range) and V-ver. (−40°C to +125°C) variants. The M306N5FCTFP#UK maintains full functionality across this range when supplied with 4.2–5.5 V.
Does the M306N5FCTFP#UK include an integrated CAN transceiver?
No, the M306N5FCTFP#UK integrates only the CAN protocol controller (CAN 2.0B compliant), not the physical layer transceiver. An external CAN transceiver such as the SN65HVD230 or TJA1042 must be used to interface with the CAN bus. The MCU provides CANRX (P9_5/CRX0) and CANTX (P9_6/CTX0) signals for connection to the transceiver's RX/TX pins.
How many analog input channels does the M306N5FCTFP#UK support?
The M306N5FCTFP#UK supports 26 analog input channels for its 10-bit A/D converter: eight channels on AN0_0–AN0_7 (P0_0–P0_7), eight on AN2_0–AN2_7 (P2_0–P2_7), and ten on AN0–AN7 plus ANEX0/ANEX1 (P10_0–P10_7, P9_5, P9_6). Channel selection is software-configurable, and conversion can be triggered internally or externally via the ADTRG pin.
What package type is used for the M306N5FCTFP#UK?
The M306N5FCTFP#UK uses the PRQP0100JB-A 100-pin plastic QFP package (14 × 20 mm, 0.65 mm lead pitch), also designated as 100P6S-A in Renesas documentation. This package is RoHS-compliant, lead-free, and compatible with standard reflow soldering profiles. Pin assignments match Figure 1.3 and Table 1.3 in the REJ03B0004-0240 datasheet.
Can the M306N5FCTFP#UK execute code from internal flash while programming another sector?
Yes, the M306N5FCTFP#UK supports Read-While-Write (RWW) operation: it can execute code from one flash block (e.g., main program area) while simultaneously erasing or programming another block (e.g., data flash block A). This enables seamless firmware updates and parameter storage without halting real-time tasks - critical for automotive and industrial control applications relying on the M306N5FCTFP#UK.
