Technical Context

The R4F2113DFT#U0 implements the H8S/2000 CPU architecture with 32-bit internal data paths and 24-bit addressing, enabling access to up to 16 MB of address space. It integrates a Clock Pulse Generator (CPG) supporting multiple clock sources (main oscillator, sub-oscillator, PLL), and a Bus State Controller (BSC) for external memory interface timing control.

Its interrupt system includes 128 vector entries, priority-based nesting, and dedicated registers for IRQ sense control, wake-up event masking, and keyboard matrix interrupt handling. The TPU provides six independent 16-bit channels with input capture, output compare, and PWM generation functions, each configurable via dedicated SFRs such as CMCSR and CMCOR.

FAQ

What is the maximum operating frequency of the R4F2113DFT#U0?

The R4F2113DFT#U0 operates at a maximum frequency of 25 MHz when powered at 3.0–5.5 V with the PLL enabled and a stable 1–20 MHz crystal connected to XTAL/EXTAL. This frequency defines the instruction cycle time (40 ns), TPU timing resolution, and SCI baud rate upper limit. The R4F2113DFT#U0 maintains full peripheral functionality-including all six TPU channels and dual LVD-across this entire speed range.

Does the R4F2113DFT#U0 support external memory expansion?

Yes, the R4F2113DFT#U0 supports external memory expansion via its expanded bus interface, configurable for 8-bit or 16-bit data width and up to 20-bit addressing (1 MB space). Control signals include AS, WR, RD, and CS, with programmable wait-state insertion through the BSC module. This capability allows direct connection to SRAM, EPROM, or peripheral ASICs without external glue logic, and is fully documented in Section 3.3 and Section 1.4.2 of the R4F2113DFT#U0 hardware manual.

How many independent low-voltage detection circuits does the R4F2113DFT#U0 integrate?

The R4F2113DFT#U0 integrates two independent low-voltage detection (LVD) circuits: LVD0 and LVD1. LVD0 monitors VCC against thresholds of 2.7 V, 2.9 V, or 3.1 V; LVD1 monitors against 4.2 V, 4.4 V, or 4.6 V. Each circuit can generate interrupts or reset signals independently, enabling tiered brown-out response-for example, LVD0 triggering graceful firmware shutdown while LVD1 initiates immediate reset during severe undervoltage. This dual-circuit architecture is confirmed in Sections 5.1 and 5.2 of the R4F2113DFT#U0 User's Manual.

What peripheral modules are included in the R4F2113DFT#U0?

The R4F2113DFT#U0 includes a 16-bit Timer Pulse Unit (TPU) with six channels, Serial Communication Interface (SCI) supporting UART protocols, Watchdog Timer (WDT), Clock Pulse Generator (CPG), Bus State Controller (BSC), Interrupt Controller (INT), and Low-Voltage Detection (LVD) circuits. It also features general-purpose I/O ports, A/D converter (in related variants), and system control registers for mode selection and reset management. All peripherals are accessible via memory-mapped SFRs and detailed in Chapters 1–7 of the R4F2113DFT#U0 hardware manual.

Is the R4F2113DFT#U0 pin-compatible with other H8S/2113 Group members?

Yes, the R4F2113DFT#U0 is pin-compatible with other 100-pin LQFP variants in the H8S/2113 Group, including R4F2112DFT#U0 and R4F2114DFT#U0. All share identical pin assignments, electrical characteristics, and mechanical footprint-enabling drop-in replacement within the same package variant. Differences lie solely in on-chip memory size (64 KB/128 KB/256 KB flash) and RAM capacity (4 KB/8 KB/16 KB), as specified in Section 1.2 "List of Products" of the R4F2113DFT#U0 User's Manual.
