TPM749
Microcontroller with TrackPoint
microcode from IBM

1996 May 01
853-1831 16753
DESCRIPTION
The Philips Semiconductors TPM749 is a small package, low cost,
ROM-coded 80C51 with IBM
’s TrackPoint
pointing algorithms
and control code. TrackPoint is the result of years of human factors
research and innovation at IBM. The result is a “velocity sensitive”
pointing solution more efficient and easier to use than “position
sensitive” devices such as the mouse, the trackball, or the touchpad.
IBM has licensed Philips Semiconductors to sell microcontrollers
with TrackPoint code. By purchasing a TPM from Philips, the
purchaser becomes a sub-licensee of Philips. The selling price of
Philips’ TPM includes the royalties for IBM’s intellectual property,
which Philips in turn pays to IBM. Customers for TPMs do not need
to sign any licensing agreement with either IBM or Philips. This code
is the intellectual property of IBM, which is covered by numerous
patents, and must be treated accordingly.
The TPM is fabricated with Philips high-density CMOS technology.
Philips epitaxial substrate minimizes CMOS latch-up sensitivity.
The TPM contains a 2k
×
8 ROM, a 64
×
8 RAM, 21 I/O lines, a
16-bit auto-reload counter/timer, a fixed-priority level interrupt
structure, an on-chip oscillator, a five channel multiplexed 8-bit A/D
converter, and an 8-bit PWM output.
The TPM supports two power reduction modes of operation referred
to as the idle mode and the power-down mode.
