Microchip Technology DSPIC30F Block Diagram

The 30 MIPS dsPIC30F families target applications that benefit from a wide operating voltage (2.5 to 5.5 volts), low standby current, integrated EEPROM, or for those that prefer 5-volt operation for system considerations. All of Microchip's DSCs have full DSP resources on-chip, including a single-cycle MAC instruction with optional saturation or rounding. The DSP engine features a high-speed, 17x17-bit multiplier, a 40-bit ALU, two 40-bit saturating accumulators and a 40-bit bidirectional barrel shifter. Bit reverse and modulo addressing is supported. Most instructions execute in a single cycle. The dsPIC30F is offered in four families.

General Purpose Family devices offer peripherals, such as a 12-bit ADC, on-chip EEPROM, up to two CAN peripherals and support for standard serial communication protocols. Selected devices offer a CODEC Interface that supports the I²S and AC97 protocols.

Motor Control and Power Conversion Family devices feature an advanced PWM with dead-band control, a 1 Msps 10-bit ADC with 4 sample and holds for optional PWM-triggered simultaneous sampling, plus a quadrature encoder interface. Some versions are offered in a 6x6 mm QFN, which enables their use on the motor or in space-constrained lighting applications. Up to 2 CAN peripherals are supported, along with other standard serial communication protocols.

Digital Power Conversion Family devices can be used for a number of digital-loop-control strategies. They feature Microchip's SMPS PWM with 1.1ns resolution; a PWM-triggered, 2 Msps 10-bit ADC with multiple Sample and Holds; and fast comparators that can be used to modify PWM cycles for current-mode operation.

Sensor Family devices feature a 12-bit ADC and small size—as small as 6x6 mm QFN.
