TPM754

The TPM754 is designed as 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 reseach 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.

TPM754 has nine features. The first one is 80C51-based architecture. The next one is small package sizes - 28-pin SSOP. The next one is power control modes include idle mode and power-down mode. The next one is 256 X 8 RAM. The next one is two 16-bit auto reloadable counter/timers. The next one is single module PCA counter/timer. The next one is it has full duplex serial channel. The next one is boolean processor. The next one is it would be CMOS and TTL compatible. That are all the main features.

Some absolute maximum ratings of TPM754 have been concluded into several points as follow. The first one is about its storage temperature range which would be from -65 to +150°C. The next one is about its voltage from Vcc to Vss which would be from -0.5V to +6.5V. The next one is about its voltage from any pin to Vss which would be from -0.5V to Vcc+0.5V. The next one is about its power dissipation which would be 1.0W.

Also there are some DC electrical characteristics about TPM754. The first one is about its input low voltage, port 1, 3 which would be min -0.5V and max 0.2Vcc - 0.1V. The next one is about its input high voltage, port 1, 3 which would be min 0.2Vcc + 0.9V and max Vcc + 0.5V. The next one is about its input high voltage, X1, RST which would be min 0.7Vcc and max Vcc+0.5V. And so on. For more information please contact us.
