TPM754A NXP Semiconductors, TPM754A Datasheet - Page 2

• Manufacturer Part Number: TPM754A
• Description: Microcontroller With Trackpoint Microcode From Ibm
• Manufacturer: NXP Semiconductors

1. PTPM754A has improved start-up from low-voltage power down.
Philips Semiconductors
The Philips Semiconductors TPM754 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 TPM754 contains IBM
PCA, a 256
two-priority level interrupt structure, a full duplex serial channel, an
on-chip oscillator, and an 8-bit D/A converter.
For identical device without TrackPoint code, see the 8XC754
datasheet.
