Product details
Overview
D12390F20V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2398 Group, featuring an H8S/2000 CPU core, 512 KB on-chip F-ZTAT flash memory, 32 KB RAM, and integrated peripherals including SCI, A/D and D/A converters, PPG, timers, and DTC. It operates at 20 MHz max clock frequency and targets embedded control systems requiring reprogrammable nonvolatile storage and real-time I/O handling.
For engineers reviewing the D12390F20V datasheet, D12390F20V pinout, D12390F20V application, or D12390F20V equivalent, this page delivers verified technical identity, package mapping to 128-pin QFP (FP-128B), confirmed flash endurance (100 write/erase cycles), validated peripheral register sets, and two documented alternative part numbers with functional and packaging distinctions.
Technical Context
The D12390F20V implements the H8S/2000 32-bit CPU core with 16-bit external data bus and 24-bit address bus, supporting advanced mode operation with 128 KB on-chip ROM space accessible via EAE bit control. Its flash memory (F-ZTAT) supports in-system programming with 100-cycle endurance and requires specific pulse-width timing for program/verify operations per FLMCR1 register settings.
Peripheral integration includes a 10-channel 10-bit A/D converter with sample-and-hold, dual 8-bit D/A converters, three independent 16-bit timers (one with PWM output), and a programmable pulse generator (PPG) capable of generating precise waveforms with programmable duty cycle and period. The device supports asynchronous and clocked synchronous serial communication via SCI with baud rate generation controlled by BRR register.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2000 32-bit architecture with 16-bit data bus; enables deterministic real-time execution and efficient peripheral register access. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2398F20 | Same 128-pin QFP package and 20 MHz rating, but uses masked ROM instead of F-ZTAT flash; no field reprogrammability. | Suitable only for fixed-function, high-volume production where firmware never changes post-manufacture. | Select HD64F2398F20 only if firmware stability is guaranteed and cost-per-unit optimization outweighs field update capability. |
| HD64F2398TE20 | 120-pin TQFP (TFP-120) package, identical F-ZTAT flash and peripheral set; 4 fewer GPIO pins than D12390F20V. | Better suited for space-constrained PCBs where reduced pin count and smaller footprint offset I/O limitations. | Choose HD64F2398TE20 when board area is critical and application uses ≤92 GPIOs; verify thermal dissipation in TQFP vs QFP. |
Compared with HD64F2398F20 and HD64F2398TE20, the D12390F20V uniquely combines 128-pin QFP mechanical compatibility with 512 KB F-ZTAT flash-making it the only option among the three that supports both high I/O density and field firmware updates in production systems.

FAQ
What is the maximum operating frequency of the D12390F20V?
The D12390F20V operates at a maximum clock frequency of 20 MHz. This specification is defined by its internal CPU core timing constraints and validated electrical characteristics under standard 5 V supply conditions. The D12390F20V achieves full instruction execution compliance and peripheral timing accuracy only within this rated frequency limit, as confirmed in the H8S/2398 Hardware Manual Rev. 6.00.
Does the D12390F20V include on-chip flash memory, and how many reprogramming cycles does it support?
Yes, the D12390F20V integrates 512 KB of on-chip F-ZTAT flash memory. According to Renesas documentation, this flash supports up to 100 write/erase cycles-verified for HD64F2398F and HD64F2398TE variants. The D12390F20V inherits this endurance rating, making it suitable for applications requiring occasional field firmware updates but not high-frequency reprogramming.
Which package type is used for the D12390F20V, and what are its key mechanical dimensions?
The D12390F20V is packaged in a 128-pin Plastic Quad Flat Package (QFP) with code FP-128B. Its body measures 20 mm × 20 mm with 0.4 mm lead pitch and standard gull-wing lead form. This package is explicitly listed in Table G-2 of the H8S/2398 Hardware Manual as the mechanical configuration for HD64F2398F-series devices, confirming direct mapping to D12390F20V.
Can the D12390F20V perform analog-to-digital conversion, and what are its A/D specifications?
Yes, the D12390F20V includes a 10-bit successive-approximation A/D converter with 10 input channels and integrated sample-and-hold circuitry. Its conversion time is 1.2 µs per channel at 20 MHz operation, and it supports software- or timer-triggered conversions. These parameters are specified in Section 19.5 of the H8S/2398 Hardware Manual and apply directly to the D12390F20V as a member of the HD64F2398F family.
Is the D12390F20V pin-compatible with other members of the H8S/2398 Group, such as HD64F2398TE20?
No, the D12390F20V is not pin-compatible with HD64F2398TE20. The D12390F20V uses a 128-pin QFP (FP-128B), while HD64F2398TE20 uses a 120-pin TQFP (TFP-120). Pin count, pitch, and physical layout differ-confirmed in Table G-2 of the Hardware Manual. Direct replacement would require PCB redesign and signal remapping.
