It supports USB 2.0 full-speed device operation, CAN 2.0B (ISO 11898-1), and capacitive touch sensing for industrial HMI applications.

For engineers reviewing the R5F52305AGFL#30 datasheet, R5F52305AGFL#30 pinout, R5F52305AGFL#30 application, or R5F52305AGFL#30 equivalent, this MCU delivers deterministic real-time control with ELC-driven event chaining, low-power software standby mode with LPT, and IEC60730-compliant self-test functions for safety-critical embedded systems.

Technical Context

The R5F52305AGFL#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 88.56 DMIPS performance at 54 MHz. It integrates a memory protection unit (MPU), on-chip debugging circuit, and dual-clock domain operation-ICLK at 54 MHz for CPU/system, PCLKA at 54 MHz for MTU2a, and PCLKD at 54 MHz for S12AD.

Its peripheral set includes a 6-channel MTU2a timer with complementary PWM and phase counting, 6-channel TPU, 4-channel DTC, and ELC enabling interrupt-free inter-module triggering. The part lacks SDHI and CAN modules per Table 1.4 (G version, 48-pin LFQFP), confirming its role as a cost-optimized variant within the RX230 Group.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F52305AGFL#30?

The R5F52305AGFL#30 operates at a maximum frequency of 54 MHz using the 32-bit RXv2 CPU core. This core implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and achieves 88.56 DMIPS. It includes an IEEE 754-compliant single-precision floating-point unit, memory protection unit (MPU), and on-chip debugging circuit-enabling deterministic real-time execution for industrial control tasks.

Does the R5F52305AGFL#30 support USB device functionality, and what speed modes are available?

Yes, the R5F52305AGFL#30 integrates a USB 2.0 host/function module supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) device operation. It includes an on-chip transceiver and internal power switch for VCC_USB, allowing operation without external power input when VCC is 4.0–5.5 V. The R5F52305AGFL#30 does not support USB host or OTG roles-only device mode-as confirmed by its RX230 Group specification and package-limited peripheral set.

Which communication interfaces are included in the R5F52305AGFL#30, and is CAN supported?

The R5F52305AGFL#30 includes USB 2.0 FS device, 4-channel SCIg (asynchronous/clock-synchronous), 1-channel I²C (RIIC), 1-channel RSPI, and IrDA (via SCI5). It does not include CAN or SDHI modules-confirmed by Table 1.4 (G version, 48-pin LFQFP) which lists "Not available" for CAN and SDHI. This distinguishes it from higher-pin-count RX231 variants and positions it for USB-centric, non-fieldbus applications.

What are the memory resources available on the R5F52305AGFL#30?

The R5F52305AGFL#30 provides 128 KB of on-chip flash memory (programmable at 1.8 V), 32 KB of SRAM with zero-wait-state access at 54 MHz, and 8 KB of data flash rated for 1,000,000 program/erase cycles. It lacks EEPROM emulation or external bus interface-consistent with its 48-pin LFQFP package constraints. These memory resources support firmware storage, real-time data buffering, and parameter retention in safety-critical applications.

What is the operating temperature range and package type of the R5F52305AGFL#30?

The R5F52305AGFL#30 is rated for −40 to +105°C operation (G version) and housed in a PLQP0048KB-B package: a 48-pin Low-Profile Quad Flat Package measuring 7 mm × 7 mm with 0.5 mm pitch, lead-free, and RoHS compliant. This package includes an exposed thermal pad and supports reflow soldering per J-STD-020, making it suitable for high-reliability industrial deployments where extended temperature stability is mandatory.
