This manual introduces how to use DWTR/FWTR for EM78P Series
This handbook explains how to operate the DWTR/FWTR programming tool, covering hardware connections, EEPROM buffer handling, and code option programming for ELAN's EM78P series microcontrollers. It is intended for engineers and technicians who need to program or update firmware on supported devices.
The document includes sections on power requirements, bus interface, OTP/FLASH IC handling, and detailed appendices listing supported EM78P part numbers and ROM data options. It also provides checksum procedures and programming application notes to ensure reliable device configuration.
| Power Supply | 18 V DC, 800 mA |
|---|---|
| Bus Interface | 40‑pin BUS |
It operates from an 18 V DC supply capable of delivering up to 800 mA.
The tool supports a wide range of EM78P devices, including EM78P154N, EM78P155N, EM78P156N, and many others listed in the appendix.
The OTP/FLASH IC stores code options and ROM data used for programming the target EM78P microcontrollers.
