Product details

Overview

M301N2F8TFP#U3 from Renesas Electronics is a 16-bit Flash-based microcontroller in the M16C/1N group, featuring an M16C/60 series CPU core, 64 KB on-chip Flash ROM, 3 KB RAM, and integrated CAN 2.0B controller - designed for automotive body control modules requiring real-time communication, analog sensing, and deterministic interrupt response.

For engineers reviewing the M301N2F8TFP#U3 datasheet, M301N2F8TFP#U3 pinout, M301N2F8TFP#U3 application, or M301N2F8TFP#U3 equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade timing and I/O specifications, and two rigorously cross-checked alternative MCUs with documented functional alignment and known substitution boundaries.

Technical Context

The M301N2F8TFP#U3 implements a silicon-gate CMOS 16-bit CPU core with 91 basic instructions and 62.5 ns minimum instruction cycle at 16 MHz XIN clock. It supports a 1 MB linear address space, dual register banks, and 20-bit program counter for extended code reach.

Its peripheral set includes a 12-channel (expandable to 14) 10-bit A/D converter, 8-bit D/A converter, three 8-bit timers (T1, TX, TY, TZ), one 16-bit timer (TC), two UART/clock-synchronous serial interfaces, and a 15-bit watchdog timer with prescaler - all mapped to dedicated SFRs and accessible via memory-mapped I/O.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	M16C/60 series 16-bit RISC-like core with dual register banks and 20-bit PC - enables efficient real-time task switching and compact firmware footprint.
Memory	64 KB Flash ROM (F0000–FFFFF₁₆) + 3 KB RAM (00400–00FFF₁₆) - supports field-upgradable firmware and sufficient data buffer for CAN message queues and sensor processing.
CAN Interface	Single-channel CAN 2.0B controller with full protocol handling, error counters, and message objects - meets ISO 11898-1 for automotive network node implementation.
Analog Peripherals	12-channel 10-bit A/D converter (with VREF input) + 8-bit D/A converter - enables direct interfacing with potentiometers, temperature sensors, and actuator feedback loops.
Timing & Power	62.5 ns min instruction time at 16 MHz XIN; 4.2–5.5 V supply range; 70 mW typical power at 5.0 V/16 MHz - ensures robust operation across automotive battery voltage transients.

Pinout & Package

Package: 48-pin LQFP (JEDEC standard 48P6Q-A, 10 mm × 10 mm, 0.5 mm pitch).

Pin/Terminal	Circuit Role	Design Meaning
P02/AN5/CTx	CAN0 transmit output / analog input / timer input	Configurable as CAN physical layer driver output (CTx) or 10-bit A/D channel 5 input - requires software selection via CIOSR register.
P03/AN4/CRx	CAN0 receive input / analog input / timer input	Configurable as CAN receiver input (CRx) or 10-bit A/D channel 4 input - supports simultaneous CAN and analog acquisition when not used for CAN.
P50(CTx)	Alternate CAN0 transmit output	Secondary CAN Tx pin; selected via software configuration in CIOSR - provides layout flexibility for PCB routing near ECU connectors.
P51(CRx)	Alternate CAN0 receive input	Secondary CAN Rx pin; selected via software configuration in CIOSR - allows differential pair placement optimization for EMC compliance.
XIN / XOUT	Main system clock oscillator terminals	Accepts ceramic resonator or crystal (1–16 MHz); internal oscillator circuit eliminates need for external clock generator in cost-sensitive designs.
VCC / VSS	Power supply and ground	4.2–5.5 V operation; decoupling capacitor (0.1 µF) required between VCC and VSS per Renesas layout guidelines to ensure stable reset and analog accuracy.

Key Features

Feature	Design Value
Flash memory programming	On-chip Flash supports in-system programming (ISP) via dedicated pins - enables firmware updates over CAN or UART without removing MCU from board.
Interrupt architecture	27 total interrupt sources (15 internal, 8 external, 4 software) with 3-bit IPL priority - guarantees deterministic latency for safety-critical CAN message handling and fault detection.
Peripheral integration	All key peripherals (CAN, UART, A/D, D/A, timers) share unified SFR map and consistent register naming - reduces driver development time and improves code portability within M16C family.
Automotive qualification	"T" suffix denotes automotive-grade screening per Renesas Standard quality grade - qualified for under-hood applications including body control units and lighting modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
R5F100PLGSP#V0	RL78/G13 16-bit core; 64 KB Flash, 4 KB RAM; no integrated CAN; requires external TJA1042 transceiver.	Lacks native CAN controller - suitable only where CAN is implemented externally or replaced by LIN/UART.	Select when migrating to Renesas' newer RL78 platform with lower power consumption but accepting added transceiver BOM and layout complexity.
MB9BF518RPMC-G-S2	Fujitsu FM3 32-bit ARM Cortex-M3; 512 KB Flash, 64 KB RAM; CAN 2.0B + USB + Ethernet MAC; 3.3 V only.	Higher performance and connectivity, but incompatible voltage domain and larger footprint - not drop-in.	Choose for next-gen systems needing CAN + USB diagnostics or OTA update capability, with full hardware redesign scope.

Compared with M301N2F8TFP#U3, R5F100PLGSP#V0 trades integrated CAN for lower active current (120 µA/MHz vs. 4.4 mA/MHz), while MB9BF518RPMC-G-S2 offers scalable connectivity at the cost of voltage compatibility and legacy toolchain support - making M301N2F8TFP#U3 optimal for cost-constrained, CAN-centric automotive nodes requiring proven qualification and minimal design change.

FAQ

What is the maximum operating frequency supported by the M301N2F8TFP#U3?

The M301N2F8TFP#U3 supports a maximum external clock frequency of 16 MHz on the XIN pin, yielding a shortest instruction execution time of 62.5 ns. This timing is guaranteed across the full 4.2–5.5 V supply range and industrial temperature range (−40°C to +85°C), as specified in the M16C/1N Group datasheet Rev.1.00.

Does the M301N2F8TFP#U3 include a hardware CAN controller?

Yes, the M301N2F8TFP#U3 integrates a single-channel CAN 2.0B-compliant controller with full message object management, error counters (C0TECR/C0RECR), and status registers (C0STR). It supports both standard and extended identifiers and operates without external protocol logic - only requiring an external CAN transceiver (e.g., TJA1042) for physical layer connection.

How much Flash and RAM memory does the M301N2F8TFP#U3 provide?

The M301N2F8TFP#U3 contains 64 KB of on-chip Flash ROM (mapped from address F0000₁₆ to FFFFF₁₆) and 3 KB of on-chip RAM (mapped from 00400₁₆ to 00FFF₁₆). These values are fixed for this specific part number and confirmed in Table 1.2 of the M16C/1N Group documentation.

Can the M301N2F8TFP#U3 operate from a 3.3 V supply?

No, the M301N2F8TFP#U3 requires a supply voltage of 4.2 V to 5.5 V for reliable operation at its rated 16 MHz clock speed. Operation below 4.2 V is not characterized or guaranteed, and attempting 3.3 V supply will result in undefined behavior, including potential failure of Flash programming, CAN communication, and A/D conversion accuracy.

What package type is used for the M301N2F8TFP#U3?

The M301N2F8TFP#U3 uses a 48-pin LQFP package conforming to JEDEC standard 48P6Q-A (10 mm × 10 mm, 0.5 mm pitch). This package is explicitly listed in Figure 1.3 and Table 1.2 of the M16C/1N Group datasheet, and the "FP" suffix in the part number directly denotes this footprint.
