Microchip Technology Inc. (NASDAQ:MCHP), a leading provider of
microcontroller and analog semiconductors, today announced six new 28-
and 44-pin 16-bit dsPIC®
Digital Signal Controllers (DSCs) with a dual-channel, 100ksps, 16-bit
audio Digital-to-Analog Conversion (DAC) module for price- or
size-conscious embedded system designers who require improved audio
performance or wish to add audio playback to existing embedded
applications.
These dsPIC DSCs are DMA-enabled with 2 Kbytes of dual-port RAM to
eliminate CPU overhead during data transfer. All feature 16 Kbytes RAM,
including dual-port RAM. The dsPIC33 devices are offered with 64 and 128
Kbytes of Flash memory, which can be used to store instructions or data.
Microchip’s DSCs feature full DSP capability
for applications that wish to process, compress or decompress audio
data. Most instructions and all DSP instructions execute in one cycle.
Microchip software libraries are available that optimize the use of
on-chip DSP resources, so designers can add DSP-enabled features without
delving into DSP technology for the remainder of their development task.
For example, several industry-standard speech-compression libraries can
be downloaded for evaluation and development at no charge, and can be
licensed for production for a low cost or free, depending on the
library. Speech-compression libraries available today include G.711 (64
kbps), ADPCM G.726A (16-40 kbps) and SPEEX (8 kbps).
Also included on the new dsPIC DSCs are two analog comparators, a
user-selectable 10- or 12-bit ADC, and a real-time clock and calendar.
Serial peripherals include 2 UARTs, 2 SPIs, I2C™
and CAN2.0B. A Parallel Master/Slave Port (PMP) enables parallel
connection to external memory, communication peripherals or displays.
The devices also include Peripheral Pin Select (PPS), which permits
digital peripherals to be remapped to other pins to achieve layout
efficiency or access to pin-multiplexed peripherals. Cyclic Redundancy
Checking (CRC) hardware is also included on-chip. All devices are
offered in Industrial (-40° to +85°C)
and Extended (-40° to +125°C)
temperature ranges.
Four of the new dsPIC33 DSCs also offer a CODEC interface supporting the
I2S and AC’97
protocols. Two of the new DSCs also offer motor control and power
conversion peripherals, including a 3-phase PWM, a power factor
correction PWM and two quadrature encoder interfaces.
Development Tools, Availability and Pricing
Volume production for all six of the new dsPIC33 controllers listed
below is expected to be in place by the end of second quarter. Prices
range from $3.67 to $4.18 each in 10,000-unit quantities. In addition to
being compatible with the free MPLAB®
IDE, which serves all of Microchip’s MCUs and
DSCs, these dsPIC33 families are supported by existing Microchip
development tools, such as the MPLAB C30 C compiler, the MPLAB ICD 2 for
programming and debugging, and the MPLAB PM3 universal device
programmer. Microchip also created the Explorer 16 development board
(part # DM240001) in support of all its 3.3V 16- and 32-bit controllers.
Additionally, Microchip offers a low cost 28-pin starter development
board (part # DM300027) for all 16-bit 28-pin devices.
Packaging options for all six of the new dsPIC33 DSCs are listed below.
