Chapter 5 MCU Programming Tools
OTP Programmer
Holtek¢s OTP devices are fully supported by a range of programmers. For engineering level OTP
device programming, Holtek supplies its stand alone programming tool which provides a quick
and efficient means for low volume OTP programming. The HT-ICE In-Circuit Emulators has inte-
grated a writer as part of the hardware package, facilitating complete design, debug and OTP de-
vice programming all within the HT-ICE. More programmers from other suppliers are available
which provide more efficient and higher volume production capability. Refer to our website for fur-
ther suppliers information.
OTP Adapter Card
The Holtek OTP programmers are supplied with a standard Textool chip socket. The OTP Adapter
Card is used to connect the Holtek OTP programmers to the various sizes of available OTP chip
packages that are unable to use this supplied socket.
