TMS320LF2407APGES Digital Signal Processors

TMS320LF2407APGES / LQFP144 / DIGITAL SIGNAL PROCESSORS & CONTROLLERS

The 240xA generation offers an array of memory sizes and different peripherals tailored to meet the specificprice/performance points required by various applications. Flash devices of up to 32K words offer acost-effective reprogrammable solution for volume production. The 240xA devices offer a password-based“code security” feature which is useful in preventing unauthorized duplication of proprietary code stored inon-chip Flash/ROM. Note that Flash-based devices contain a 256-word boot ROM to facilitate in-circuitprogramming.

The 240xA family also includes ROM devices that are fully pin-to-pin compatible with their Flashcounterparts.All 240xA devices offer at least one event manager module which has been optimized for digital motor controland power conversion applications. Capabilities of this module include center- and/or edge-aligned PWMgeneration, programmable deadband to prevent shoot-through faults, and synchronized analog-to-digitalconversion. Devices with dual event managers enable multiple motor and/or converter control with a single240xA DSP controller. Select EV pins have been provided with an “input-qualifier” circuitry, which minimizesinadvertent pin-triggering by glitches．
