Renesas R5F36CAENFB#30

Overview

R5F36CAENFB#30 from Renesas Electronics is a 16-bit flash microcontroller based on the M16C/60 Series CPU core, featuring 256 KB program ROM, 16 KB RAM, 20 KB data flash, USB 2.0 Full Speed interface, 10-bit A/D converter (26 channels), and three-phase motor control timers. It operates at 32 MHz with supply voltage 2.7–5.5 V and targets consumer-grade embedded systems including audio components, cameras, and office equipment.

For engineers reviewing the R5F36CAENFB#30 datasheet, R5F36CAENFB#30 pinout, R5F36CAENFB#30 application, or R5F36CAENFB#30 equivalent, key selection considerations include its 100-pin LQFP package (PLQP0100KB-A), dual power supply (VCC1/VCC2), integrated USB PHY, real-time clock, and support for external bus expansion up to 1 MB address space.

Technical Context

The R5F36CAENFB#30 implements a 16-bit M16C/60 CPU core with hardware multiplier (16×16→32 bit) and multiply-accumulate capability, executing instructions in as little as 31.25 ns at 32 MHz. Its memory architecture supports single-chip, memory expansion, and microprocessor modes, with separate VCC1 (core/analog) and VCC2 (bus I/O) supplies enabling mixed-voltage interfacing.

Peripheral integration includes six UARTs with I²C-bus and IEBus support, a multi-master I²C interface, five 16-bit Timer A units (with PWM and encoder input), six 16-bit Timer B units (including three-phase inverter control with on-chip dead time), and dedicated USB 2.0 Full Speed module with 584-byte FIFO and four transfer types (Control, Bulk IN/OUT, Interrupt IN).

FAQ

What is the maximum operating frequency and supply voltage range for the R5F36CAENFB#30?

The R5F36CAENFB#30 operates at a maximum frequency of 32 MHz with a minimum instruction execution time of 31.25 ns. It supports a supply voltage range of 2.7 V to 5.5 V on VCC1 (core/analog) and VCC2 (bus I/O), where VCC2 must be ≤ VCC1. This dual-supply architecture enables flexible interfacing with both 3.3 V and 5 V external peripherals without level shifters.

Does the R5F36CAENFB#30 include an integrated USB transceiver, and what USB speed does it support?

Yes, the R5F36CAENFB#30 integrates a full-speed USB 2.0 transceiver compliant with USB Specification Rev. 2.0. It supports 12 Mbps data transfer with dedicated D+ and D- pins, internal 1.5 kΩ pull-up control via the ATTACH signal, and VBUS detection through the VbusDTCT pin. The 584-byte FIFO and endpoint buffers eliminate the need for external USB interface ICs in standard peripheral implementations.

How many analog input channels does the R5F36CAENFB#30 support, and what is the A/D conversion performance?

The R5F36CAENFB#30 supports 26 analog input channels across two 10-bit A/D converter circuits. Conversion time is 1.72 µs per sample, and inputs include AN0–AN7, AN0_0–AN0_7, AN2_0–AN2_7, and extended pins ANEX0/ANEX1. Reference voltage is configurable via the VREF pin, and the AVCC/AVSS power domain ensures noise-immune analog operation independent of digital switching.

What package type and pin count does the R5F36CAENFB#30 use, and is it RoHS-compliant?

The R5F36CAENFB#30 uses a 100-pin LQFP package designated PLQP0100KB-A (formerly 100P6Q-A), measuring 14 mm × 14 mm with 0.5 mm lead pitch. It is RoHS-compliant and designed for surface-mount reflow assembly. Pin assignments match the M16C/6C Group family standard, and the package supports both single-chip and memory expansion modes without modification.

Can the R5F36CAENFB#30 perform three-phase motor control, and which peripherals enable this function?

Yes, the R5F36CAENFB#30 provides hardware-accelerated three-phase motor control using Timer A1, A2, A4 and Timer B2 in coordinated mode, with dedicated U/V/W output pins and an on-chip dead-time timer. These resources generate complementary PWM signals with programmable dead time to prevent shoot-through in inverter bridges-enabling direct control of BLDC or PMSM motors without external gate drivers or timing logic.
