TMS320C5532AZAYA05

Digital Signal Processor Dsp Overview

The TMS320C5532AZAYA05 is a fixed-point digital signal processor from the C5000 family, operating at a maximum clock rate of 50 MHz with a 20-ns instruction cycle time. It utilizes the low-power C55x DSP core architecture and includes 64 KB of on-chip dual-access RAM (DARAM) and 128 KB of on-chip ROM. The device operates with a 1.05-V core voltage and supports I/O voltages of 1.8 V, 2.5 V, 2.75 V, or 3.3 V. Key peripherals include four DMA controllers, two SD interfaces, four I2S modules, an RTC, and GPIOs. It is housed in a 144-terminal BGA package.

Digital Signal Processor Dsp Feature Summary

• C55x DSP Core: High-performance, low-power architecture with up to 200 million MAC operations per second.
• Memory Configuration: 64 KB DARAM and 128 KB ROM; lacks SARAM compared to higher-tier models.
• Peripheral Set: Includes four I2S buses, two SD/eMMC interfaces, UART, SPI, I2C, and three 32-bit timers.
• Power Management: Features integrated ANA_LDO for analog circuits; lacks internal DSP_LDO and USB_LDO.

Digital Signal Processor Dsp Applications

• Wireless audio devices such as headsets and microphones
• Voice applications and echo cancellation headphones
• Portable medical devices
• Industrial controls

Digital Signal Processor Dsp Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature range and packaging configuration. Confirm that the absence of internal DSP_LDO and USB_LDO aligns with the external power supply design, as these domains require independent voltage regulation.

Digital Signal Processor Dsp Selection Notes

Select this model over the TMS320C5535 when USB connectivity and FFT acceleration are not required. Note that the TMS320C5532 lacks the 256 KB SARAM found in the C5535 and does not include the SAR ADC or LCD Bridge peripheral.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C553x series, which shares the same 144-pin BGA package and base C55x CPU core. The TMS320C5532 represents the entry-level variant within this group, distinguished by its reduced memory capacity and exclusion of high-speed USB and hardware FFT accelerator features.
