Technical Context
The R5F52305ADFP#30 belongs to the RX230 Group and implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, memory protection unit (MPU), and fast interrupt response. Its clock system supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), and USB-dedicated PLL (4/6/8/12 MHz), enabling independent 54 MHz system clock and 48 MHz USB clock generation.
Peripheral integration includes ELC for event-driven module triggering without CPU intervention, DTC for interrupt-triggered data transfers, and TSIP-Lite for AES-128/256 encryption with true random number generation. The device supports three low-power modes and operates across 1.8–5.5 V with −40 to +85°C temperature range.

FAQ
What is the maximum operating frequency of the R5F52305ADFP#30?
The R5F52305ADFP#30 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS performance. This speed is achievable across its full 1.8–5.5 V supply range, with no wait states on SRAM access and optimized flash accelerator behavior above 32 MHz. The R5F52305ADFP#30 achieves this via its RXv2 CPU core with 5-stage pipeline and variable-length instruction set.
Does the R5F52305ADFP#30 include a real-time clock (RTC)?
No, the R5F52305ADFP#30 does not include an RTC module. RTC functionality is present in higher variants like R5F52315ADFP#30 and R5F52316ADFP#30 within the RX230 Group, but it is explicitly omitted from the R5F52305ADFP#30 per Table 1.2 of the datasheet. Designers requiring calendar/timekeeping must select an alternate part or implement external RTC circuitry.
What package type is used for the R5F52305ADFP#30?
The R5F52305ADFP#30 uses a 100-pin LFQFP package designated PLQP0100KB-B: 14 × 14 mm body size with 0.5 mm pitch, lead-free and RoHS-compliant. This package provides 79 general-purpose I/O pins and supports all peripheral functions specified for the RX230 Group in the 100-pin configuration, including full USB DP/DM and CANH/CANL routing.
Can the R5F52305ADFP#30 execute AES encryption in hardware?
Yes, the R5F52305ADFP#30 includes TSIP-Lite - a hardware cryptographic engine supporting AES-128 and AES-256 in ECB, CBC, GCM, and other modes, along with a true random number generator and secure key management. This enables authenticated firmware updates, encrypted sensor data storage, and secure boot without software-only crypto overhead.
How many analog-to-digital converter channels does the R5F52305ADFP#30 support?
The R5F52305ADFP#30 integrates a 12-bit successive-approximation ADC (S12ADE) with 24 input channels. Each channel supports programmable sampling time, and the module offers scan modes (single, continuous, group), self-diagnostic capability, and analog input disconnection detection - all confirmed in the R01DS0261EJ0120 datasheet for the RX230 Group.
