MSP50C33 Datasheet Mixed-signal Processors

Manufacturer: Texas Instruments

Overview: D Dual Programmable LPC-12 Speech Synthesizers D Simultaneous LPC and PCM Waveforms D 8-Bit Microprocessor with 61 instructions D 32 Twelve-Bit Words and 224 Bytes of RAM D 3.3V to 6.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MSP50x3x family uses a revolutionary architecture to combine an 8-bit microprocessor, two speech synthesizers, ROM, RAM, and I/O in a low-cost single-chip system.

The architecture uses the same arithmetic logic unit (ALU) for the two synthesizers and the microprocessor, thus reducing chip area and cost and enabling the microprocessor to do a multiply operation in 0.8 µs.

The MSP50x3x family

Key Features

  • two independent channels of linear predictive coding (LPC), which synthesize high-quality speech at a low data rate. Pulse-code modulation (PCM) can produce music or sound effects. LPC and PCM can be added together to produce a composite result. For more information, see the MSP50x3x User’s Guide (literature number SPSU006). Table 1.
