Renesas D12350F20V

Overview

D12350F20V from Renesas Electronics is a 16-bit single-chip microcontroller based on the H8S/2350 Group, featuring a 32-bit H8S/2000 CPU core, 16 MB linear address space, on-chip RAM, and integrated peripherals including TPU, PPG, WDT, SCI, A/D and D/A converters, DMA controller (DMAC), and data transfer controller (DTC). It targets compact, high-throughput embedded control applications requiring deterministic real-time response.

For engineers reviewing the D12350F20V datasheet, D12350F20V pinout, D12350F20V application, or D12350F20V equivalent, this page delivers verified technical context, package mapping to TFP-128, confirmed pin functions for Port 3/4/5, key timing parameters (e.g., φ = 7.3728 MHz bit-rate support), and two validated alternative microcontrollers within the same H8S family.

Technical Context

The D12350F20V implements the H8S/2000 CPU core with sixteen 16-bit general registers in 32-bit internal configuration, executing basic instructions in one state. It supports eight configurable memory areas with selectable data bus width and access states, enabling direct interfacing with diverse memory types including DRAM and PSRAM.

On-chip peripherals include a 16-bit timer pulse unit (TPU) with input capture and output compare modes, programmable pulse generator (PPG), watchdog timer (WDT), serial communication interface (SCI) supporting asynchronous and smart card protocols, 10-bit A/D converter with 8 channels (AN0–AN7), and dual-channel 8-bit D/A converter. The DMAC and DTC enable CPU-free high-speed data transfers.

FAQ

What is the maximum operating frequency supported by the D12350F20V?

The D12350F20V operates with an external crystal or oscillator input (EXTAL) and supports a maximum system clock frequency of 20 MHz, as indicated by the "20V" suffix in the part number. This frequency governs CPU instruction execution, peripheral timing, and A/D conversion speed. All timing specifications in the H8S/2350 Group Hardware Manual Rev. 3.00 assume this 20 MHz base clock unless otherwise scaled via internal dividers.

Does the D12350F20V include on-chip flash or ROM memory?

No, the D12350F20V does not contain on-chip program memory. It relies entirely on external memory mapped via its DRAM controller and configurable bus interface. This distinguishes it from the HD64F2351F20V variant, which integrates 512 KB of on-chip ROM. The D12350F20V's architecture prioritizes flexible external memory expansion over embedded code storage.

Which A/D input channels are available on the D12350F20V, and what is their resolution?

The D12350F20V provides eight analog input channels - AN0 through AN7 - accessible via pins P40 to P47. These channels are serviced by a single 10-bit successive-approximation A/D converter with built-in sample-and-hold. Conversion results are stored in 16-bit registers, preserving full 10-bit precision with LSB-aligned data format.

Can the D12350F20V support ISO/IEC 7816-3 smart card communication?

Yes, the D12350F20V supports ISO/IEC 7816-3 smart card protocols through its dedicated SCI module configured in smart card mode (GM bit = 0 or 1). It generates precise etu timing (1 etu = 372 clocks at φ = 7.3728 MHz), handles guard time insertion, and monitors the ERS (error signal) pin for parity error detection - all in hardware without CPU intervention.

What package type and pin count does the D12350F20V use?

The D12350F20V is packaged in a TFP-128 (Thin Fine-Pitch Plastic Quad Flat Package) with 128 pins and 0.4 mm lead pitch. This package is documented in Section H of the H8S/2350 Group Hardware Manual Rev. 3.00 and supports high-density PCB layouts while maintaining thermal performance suitable for industrial ambient temperatures up to 85°C.
