Product details
Overview
R5F36406CNFB#30 from Renesas Electronics is a 16-bit M16C/60 Series microcontroller with 128 KB program ROM, 12 KB RAM, and 4 KB × 2 data flash, housed in a 100-pin LQFP (PLQP0100KB-A) package. It operates at up to 25 MHz (40 ns min instruction time), integrates a 16×16-bit multiplier, real-time clock, three-phase motor control timers, 26-channel 10-bit A/D converter, dual 8-bit D/A converters, and CEC interface - enabling use in industrial motor drives and HDMI-CEC–enabled consumer audio/video systems.
For engineers reviewing the R5F36406CNFB#30 datasheet, R5F36406CNFB#30 pinout, R5F36406CNFB#30 application, or R5F36406CNFB#30 equivalent, key selection considerations include its -20°C to +85°C operating temperature, dual power supply (VCC1/VCC2) for mixed-voltage bus interfacing, 1 MB expandable address space, and support for both single-chip and memory expansion modes.
Technical Context
The R5F36406CNFB#30 implements the M16C/60 CPU core with two register banks, 20-bit program counter, and hardware multiplier supporting 16×16→32-bit multiply and MAC operations. Its memory architecture includes separate 128 KB program ROM 1, 12 KB RAM, and dual 4 KB data flash blocks - each independently erasable and programmable at 2.7–5.5 V.
Peripheral integration centers on deterministic real-time control: five 16-bit Timer A units (with PWM, encoder input, dead-time generation), six 16-bit Timer B units (pulse width/period measurement), multi-master I²C, six UART channels, two remote control signal receivers (32 kHz), and dedicated CEC transceiver with arbitration and ACK auto-generation - all synchronized to a flexible clock system with PLL, sub-clock, and 125 kHz on-chip oscillator.

FAQ
What is the operating temperature range for the R5F36406CNFB#30?
The R5F36406CNFB#30 is rated for operation from -20°C to +85°C. This specification is confirmed in Table 1.3 of the R01DS0016EJ0110 datasheet under "Product List (N-Version)", where the "N" suffix denotes the -20°C to +85°C grade. The device does not support the extended -40°C to +85°C range indicated for "D-Version" parts like R5F36406CDFB#30.
Does the R5F36406CNFB#30 support external memory expansion?
Yes, the R5F36406CNFB#30 supports external memory expansion with a base 1 MB address space (00000h–FFFFFh) expandable to 4 MB using the memory area expansion function. It provides four chip-select outputs (CS0–CS3), configurable wait states (0–3), and flexible bus formats (separate or multiplexed) with selectable 8- or 16-bit data width - as detailed in Table 1.1 "Specifications for the 100-Pin Package".
What are the key differences between R5F36406CNFB#30 and R5F36406CNFA#30?
The R5F36406CNFB#30 and R5F36406CNFA#30 share identical electrical specifications, memory configuration (128 KB ROM, 12 KB RAM), peripherals, and temperature rating (-20°C to +85°C). Their sole difference is package type: R5F36406CNFB#30 uses 100-pin LQFP (PLQP0100KB-A), while R5F36406CNFA#30 uses 100-pin QFP (PRQP0100JD-B) - confirmed in Tables 1.3 and 1.4 of the datasheet.
How is the CEC functionality implemented in the R5F36406CNFB#30?
The R5F36406CNFB#30 implements CEC via a dedicated on-die transceiver accessible through pin P8_5 (NMI/SD/CEC). It supports full CEC protocol operation at 32 kHz, including transmit/receive, arbitration loss detection, and automatic ACK output - as specified in Table 1.2 and Figure 1.3 "Block Diagram". No external PHY or level-shifting components are required.
Can the R5F36406CNFB#30 operate with different supply voltages on VCC1 and VCC2?
Yes, the R5F36406CNFB#30 supports dual-supply operation: VCC1 (2.7–5.5 V) powers the core and analog peripherals, while VCC2 (2.7 V to VCC1) powers the external bus interface. This allows interfacing with 3.3 V logic while driving 5 V peripherals - explicitly stated in Table 1.7 "Pin Functions" and Section 1.6 "Pin Functions" of the datasheet.
