Overview
M306N4MGT-158FPUFL from Renesas Electronics is a 16-bit microcontroller in the M16C/6N Group (M16C/6N4), built on high-performance silicon gate CMOS with the M16C/60 Series CPU core. It features 256 KB mask ROM, 10 KB RAM, dual CAN 2.0B modules, 10-bit A/D converter (26 channels), and 8-bit D/A converter (2 channels), operating at up to 24 MHz (VCC = 4.2–5.5 V) for automotive T-version applications.
For engineers reviewing the M306N4MGT-158FPUFL datasheet, M306N4MGT-158FPUFL pinout, M306N4MGT-158FPUFL application, or M306N4MGT-158FPUFL equivalent, this MCU is selected for deterministic real-time control in CAN-based automotive subsystems, industrial motor drives, and embedded systems requiring integrated analog I/O, timer peripherals, and memory expansion capability.
Technical Context
The M306N4MGT-158FPUFL implements the M16C/60 Series CPU core with 91 fundamental instructions and minimum instruction execution time of 41.7 ns at 24 MHz (1/1 prescaler, no wait states). Its architecture supports single-chip, memory expansion, and microprocessor modes with 1 Mbyte address space and four clock generation circuits - including main/sub oscillators, on-chip oscillator, and PLL frequency synthesizer.
