DSP CONTROLLERS

The TMS320LF2407A TMS320LF2406A TMS320LF2403A TMS320LF2402A TMS320LC2406A TMS320LC2404A TMS320LC2403A TMS320LC2402A devices, new members of the TMS320C24x generation of digital signal processor (DSP) controllers, are part of the TMS320C2000 platform of fixed-point DSPs The 240xA devices offer the enhanced TMS320 DSP architectural design of the C2xx core CPU for low-cost, low-power, and high-performance processing capabilities. Several advanced peripherals, optimized for digital motor and motion control applications, have been integrated to provide a true single-chip DSP controller. While code-compatible with the existing C24x DSP controller devices, the 240xA offers increased processing performance (40 MIPS) and a higher level of peripheral integration. See the TMS320x240xA Device Summary section for device-specific features. The 240xA generation offers an array of memory sizes and different peripherals tailored to meet the specific price/performance points required by various applications. Flash devices of up to 32K words offer a cost-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 in on-chip Flash ROM. Note that Flash-based devices contain a 256-word boot ROM to facilitate in-circuit programming. The 240xA family also includes ROM devices that are fully pin-to-pin compatible with their Flash counterparts. All 240xA devices offer at least one event manager module which has been optimized for digital Motor Control and power conversion applications. Capabilities of this module include center- and/or edge-aligned PWM generation, programmable deadband to prevent shoot-through faults, and synchronized Analog-to-digital conversion. Devices with dual event managers enable multiple motor and/or converter control with a single 240xA DSP controller. Select EV pins have been provided with an input-qualifier circuitry, which minimizes inadvertent pin-triggering by glitches. The high-performance, 10-bit Analog-to-digital converter (ADC) has a minimum conversion time of 375 ns and offers up to 16 channels of Analog input. The autosequencing capability of the ADC allows a maximum of 16 conversions to take place in a single conversion session without any CPU overhead. By Texas Instruments
