CMOS 8–Bit Microcontrollers
1. Outline and Characteristics
The TMP90PH44 is a system evaluation LSI having a built-in
One-Time PROM for (16K byte) for TMP90C844.
A programming and veriﬁcation for the internal PROM is
achieved by using a general EPROM programmer with an
The function of this device is exactly the same as the
TMP90C844 by programming to the internal PROM.
The different points between TMP90PH44 and
TMP90C844 are the memory size (ROM/RAM).
The TMP90PH44N is in a Shrink Dual Inline Package.
The TMP90PH44F is in a Quad Flat Package.
