DS553PP3
DSP MAC is pipelined, 1 cycle / multiply
Includes 32 hardware lockable semaphore registers
Two general-purpose registers for inter-processor communication
Three 32-bit timers for I/O and other uses, with programmable interval rates
“Getbits” module accelerates peripheral stream parsing
Both hardware and software interrupts on data or debug
Large internal SRAM (80 Kbyte) and internal program ROM (256 Kbyte)
Supports both Synchronous and EDO DRAM (256 KBytes to 8 MBytes) for ESP
Supports one bank of FLASH and ROM (up to 2 MBytes) for nonvolatile storage
4-, 8-, or16-bit data bus for DRAM, 8-bit data bus for ROM
Glueless interfaces to CD servo chip set, supporting all standard CD formats
Includes pattern matching hardware to support fast ESP recovery
Supports 4 channels PCM, I
Flexible audio clocking scheme using internal PLL and dividers, or external pins
Simultaneous IEC-958 output with programmable channel status and user data
Integrated sigma-delta (∆Σ) stereo audio modulator
2-wire serial slave port, used for debug
3- or 4-wire synchronous serial master/slave port for external controller or slave peripheral
Separate synchronous serial master port optimized for receiving CD sub-codes
Up to 29 programmable bi-directional I/O (GPIO) and up to 9 output only (GPO) pins (some multi-
plexed with other peripherals)
All pins defined as GPIOs can be used to receive edge or level detection interrupts.
Pulse-width modulated (PWM) output pin can be used to create simple ADC using low-cost compar-
ator (i.e., for battery voltage monitor)
Internal oscillator uses external crystal, or receives clock (i.e. 16.9 MHz) from CD servo
Internal PLL generates any system clock frequency, chip can run up to 90 MHz
Includes clock divider and clock shutoff circuits for low power/sleep modes
Advanced 0.18 micron CMOS technology, runs off 1.8 V and 3.3 V
All I/O pins are 3.3 V, with 5 V tolerance
100-pin LQFP package
Lead-free/industrial temperature range parts available
