Product details
Overview
TMS320C50PQA57 from Texas Instruments is a 16-bit fixed-point digital signal processor (DSP) designed for real-time signal processing in embedded systems, featuring 50-ns single-cycle instruction execution at 5 V, 9K × 16-bit on-chip program ROM, 1K × 16-bit dual-access RAM (DARAM), and a 132-pin PQ package. It supports full-duplex synchronous serial port, hardware wait-state generation, and on-chip timer for control-intensive applications such as voice coding and motor control.
For engineers reviewing the TMS320C50PQA57 datasheet, TMS320C50PQA57 pinout, TMS320C50PQA57 application, or TMS320C50PQA57 equivalent, key selection criteria include its 5-V operation, 132-pin QFP footprint, Harvard architecture memory mapping (64K program/64K data/64K I/O space), host port interface absence, and compatibility with TI's C5x development tools and legacy C1x/C2x source code.
Technical Context
The TMS320C50PQA57 implements an advanced static CMOS Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and operand access. Its CPU executes up to 20 MIPS at 50 ns/cycle and integrates on-chip peripherals including a full-duplex synchronous serial port, time-division-multiplexed (TDM) serial port, and boundary-scan JTAG test logic per IEEE 1149.1.
It supports multiple clocking modes via PLL with ×1, ×2, ×3, ×4, or ×5 multiplication factors and includes power-down modes (IDLE1, IDLE2) achieving 10 mA and 3 mA current draw respectively at 40 MHz. Memory management features block moves, repeat instructions, and hardware/software wait-state generation for flexible external memory interfacing.

FAQ
What is the maximum operating frequency of the TMS320C50PQA57?
The TMS320C50PQA57 supports a 50-ns instruction cycle time at 5 V, corresponding to a maximum system clock frequency of 20 MHz. This timing is guaranteed across commercial temperature range (0°C to 70°C) and enables deterministic execution of real-time signal processing algorithms without pipeline interlocks.
Does the TMS320C50PQA57 include a host port interface (HPI)?
No, the TMS320C50PQA57 does not include a host port interface. HPI is present only on specific variants like TMS320C57S and TMS320LC57S (PGE package). The TMS320C50PQA57 relies on its parallel I/O bus (A0–A15, D0–D15, PS/DS/IS, R/W) and serial ports for external communication.
What memory types and capacities are integrated into the TMS320C50PQA57?
The TMS320C50PQA57 integrates 9K × 16-bit on-chip program ROM, 1K × 16-bit dual-access RAM (DARAM), and 544-word + 512-word single-access RAM (SARAM). These memories support zero-wait-state execution and data buffering, eliminating need for external SRAM in many standalone applications.
Which serial interfaces are supported by the TMS320C50PQA57?
The TMS320C50PQA57 supports two serial interfaces: a full-duplex synchronous serial port (with DR, DX, CLKR, CLKX, FSR, FSX) and a time-division-multiplexed (TDM) serial port (with TDR, TDX, TCLKR, TCLKX, TFSR/TADD, TFSX/TFRM). Both operate independently and can be used simultaneously.
Is the TMS320C50PQA57 pin-compatible with other TMS320C5x devices in the PQ package?
Yes, all TMS320C5x devices in the 132-pin PQ package - including TMS320C50, TMS320LC50, TMS320C51, and TMS320LC51 - share identical pinouts and mechanical footprint. Functional differences (e.g., voltage, memory size, TDM presence) do not affect PCB layout, enabling drop-in replacement within the same package family.
