Product details

Overview

UPD78F9500MA(S)-CAC-A from Renesas Electronics is a 16-pin interface adapter that converts the 14-pin E1 emulator interface to the 16-pin interface used by QB-MINI2 and PG-FP5 programmers. It supports clock frequencies of 4/8/16 MHz, includes JP2 and JP3 jumper pads for UART programming/debugging mode selection, and is mechanically designed for direct board-level interconnection between Renesas debug tools and target 78K0-family microcontrollers.

For engineers reviewing the UPD78F9500MA(S)-CAC-A datasheet, UPD78F9500MA(S)-CAC-A pinout, UPD78F9500MA(S)-CAC-A application, or UPD78F9500MA(S)-CAC-A equivalent, this adapter enables hardware-compatible debugging and flash programming workflows across Renesas 78K0-based development systems using standardized E1-to-16-pin conversion.

Technical Context

The UPD78F9500MA(S)-CAC-A implements passive signal routing between two standardized Renesas debug interfaces: it maps E1's 14-pin layout (including TRST, TCK, TMS, TDI, TDO, RESET, VDD, GND, and clock lines) to the 16-pin QB-MINI2/PG-FP5 footprint with dedicated JP2 and JP3 jumpers for UART path control. No active logic or voltage translation is present.

It supports three operational modes defined by jumper states: default (shorted) for standard debugging, JP2 open for external UART sharing during debug, and JP3 open for specific 78K0/Kx1+ variants (e.g., uPD78F0711/0712/0714) during flash programming. Clock delivery is limited to 4/8/16 MHz only.

Key Specifications

FAQ

What is the primary function of the UPD78F9500MA(S)-CAC-A?

The UPD78F9500MA(S)-CAC-A is a passive mechanical and signal-routing adapter that converts the 14-pin interface of the Renesas E1 emulator to the 16-pin interface required by QB-MINI2 and PG-FP5 programmers. It enables compatibility between older debug hardware and newer programming tools for 78K0-family microcontrollers without modifying target board layouts or adding active circuitry.

Which microcontroller families are explicitly supported by the UPD78F9500MA(S)-CAC-A?

The UPD78F9500MA(S)-CAC-A is validated for use with Renesas 78K0-family microcontrollers, including 78K0/Kx1+, uPD78F0711, uPD78F0712, and uPD78F0714. Its JP3 jumper configuration is specifically defined for these parts during flash programming, confirming functional alignment with this MCU group.

Does the UPD78F9500MA(S)-CAC-A provide voltage level translation or signal conditioning?

No, the UPD78F9500MA(S)-CAC-A provides no voltage translation, buffering, or signal conditioning. It is a passive pin-mapping adapter with direct copper traces and solder-jumper pads (JP1–JP3). Signal integrity and voltage compatibility must be maintained by the connected E1 emulator, target MCU, and programmer - all operating within Renesas' specified 3.3 V or 5 V logic domains.

How do JP2 and JP3 affect the operation of the UPD78F9500MA(S)-CAC-A?

JP2 controls UART path isolation: open during debug when external devices share the UART line; shorted (default) otherwise. JP3 enables variant-specific flash programming: open for uPD78F0711/0712/0714 and 78K0/Kx1+ during programming; shorted (default) for debug. Both jumpers are physical solder pads, not switchable connectors.

Is the UPD78F9500MA(S)-CAC-A compatible with non-Renesas debug tools or MCUs?

No official compatibility is documented for non-Renesas tools or MCUs. The UPD78F9500MA(S)-CAC-A is engineered exclusively for Renesas E1 emulators and QB-MINI2/PG-FP5 programmers targeting 78K0-family microcontrollers. Pin assignments, signal definitions, and jumper behaviors align only with Renesas' debug interface specifications.
