Product details
Overview
UPD78F9500MA-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 configurable jumpers (JP1–JP3) for UART programming/debugging isolation, and is designed for use with 78K0-family microcontrollers including uPD78F0711/0712/0714.
For engineers reviewing the UPD78F9500MA-CAC-A datasheet, UPD78F9500MA-CAC-A pinout, UPD78F9500MA-CAC-A application, or UPD78F9500MA-CAC-A equivalent, this adapter enables interoperability between legacy E1 debug hardware and newer Renesas programming tools while maintaining signal integrity and configuration flexibility for flash programming and real-time debugging workflows.
Technical Context
The UPD78F9500MA-CAC-A implements passive pin mapping between two standardized Renesas debug interfaces: it routes signals such as RESET, CLK, TXD, RXD, VDD, and GND between the 14-pin E1 header and the 16-pin target header without level shifting or buffering. Jumper JP2 isolates external UART connections during debugging; JP3 enables/disables specific 78K0/Kx1+ device programming modes.
Signal routing follows Renesas' documented pin-exchange convention (R20UT0544XJ0200 Rev.2.00), with no active components or power regulation. The board-level pattern-cut option allows permanent circuit disconnection for specialized isolation requirements - a design feature confirmed in the official user manual's "Note" section.

FAQ
What is the primary function of the UPD78F9500MA-CAC-A?
The UPD78F9500MA-CAC-A is a passive pin-mapping adapter that converts the 14-pin E1 emulator interface to the 16-pin interface required by QB-MINI2 and PG-FP5 programmers. It enables compatibility between older Renesas debug hardware and newer programming tools without signal conditioning or voltage translation - all routing is direct and verified per R20UT0544XJ0200.
Which microcontroller families are explicitly supported by the UPD78F9500MA-CAC-A?
The UPD78F9500MA-CAC-A is explicitly validated for use with Renesas 78K0-family MCUs, including 78K0/Kx1+ variants and specific models listed in the manual: uPD78F0711, uPD78F0712, and uPD78F0714. Support is limited to these devices per Section 4 of R20UT0544XJ0200 Rev.2.00.
How do JP2 and JP3 jumpers affect UPD78F9500MA-CAC-A operation?
JP2 must be open during debugging when the target system's UART is shared with external peripherals; it is shorted (default) during flash programming. JP3 must be open when programming uPD78F0711/0712/0714 or 78K0/Kx1+ devices; it is shorted (default) during debugging - both configurations are mandatory per R20UT0544XJ0200.
Does the UPD78F9500MA-CAC-A provide clock generation or signal conditioning?
No. The UPD78F9500MA-CAC-A contains no active components, oscillators, or level shifters. Clock signals (4/8/16 MHz) are passed directly from the E1 emulator; all signal routing is passive and impedance-uncompensated. Any timing compliance depends entirely on the source E1 emulator and target MCU's interface specifications.
Can the UPD78F9500MA-CAC-A be used with non-Renesas debug tools?
No. The UPD78F9500MA-CAC-A is engineered exclusively for Renesas E1 emulators on the 14-pin side and QB-MINI2/PG-FP5 programmers on the 16-pin side. Pin assignments, signal definitions, and jumper logic follow Renesas-specific conventions documented in R20UT0544XJ0200 - use with third-party tools is neither specified nor supported.
