PIIPM15P12D007 System Block Schematic:
Description
The PIIPM15P12D007 is a fully integrated Intelligent Power
Module for high performances Servo Motor Driver
applications.
The device core is a state of the art DSP, the
TMS320LF2406A at 40 Mips, interfaced with a full set of
peripherals designed to handle all analog feedback and
control signals needed to correctly manage the power
section of the device. A 64kbits EEPROM is also available to
store calibration data. The PIIPM has been designed and
tailored to implement internally all functions needed to close
the current, speed and position loops of a high performances
servo motor driver.
The use of the flash memory version of the DSP and the
JTAG port connector allows the user to easily develop and
download his own proprietary algorithm.
The device comes in the EMP package, fully compatible in
length, width and height with the popular EconoPack 2
outline.
