2 / 14 page Philips Semiconductors Product specification TPM749 Microcontroller with TrackPoint ™ microcode from IBM 2 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.
