Product details
Overview
TMS320C5532AZHH10 from Texas Instruments is a fixed-point digital signal processor (DSP) optimized for ultra-low-power audio and voice processing in battery-operated devices. It features a 100-MHz C55x CPU core, 64KB on-chip dual-access RAM (DARAM), 128KB ROM, four I²S interfaces, real-time clock (RTC), and 32 GPIO pins multiplexed with peripheral functions. It targets portable medical devices, wireless headsets, and industrial control edge nodes requiring deterministic low-latency signal processing.
For engineers reviewing the TMS320C5532AZHH10 datasheet, TMS320C5532AZHH10 pinout, TMS320C5532AZHH10 application, or TMS320C5532AZHH10 equivalent, this page delivers verified specifications, package mapping, functional context, and validated alternative options - all grounded in TI's SPRS737C Production Data documentation.
Technical Context
The TMS320C5532AZHH10 implements the TMS320C55x DSP architecture with two 17×17-bit MAC units, dual ALUs, and a 40-bit accumulator, enabling up to 200 MMACS at 100 MHz. Its internal bus structure supports four 16-bit data reads and two 16-bit writes per cycle, maximizing parallelism while minimizing active power consumption.
It integrates four independent DMA controllers (16 total channels), a software-programmable PLL (multiplier x4–x4099), and three isolated power domains (ANA, RTC, peripherals). Unlike C5535/C5534, it omits USB PHY, LCD bridge, SAR ADC, and FFT hardware accelerator - reducing die size and static power for cost- and power-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | TMS320C55x fixed-point DSP with dual MAC, dual ALU, and 40-bit accumulator - enables real-time FIR/IIR filtering and echo cancellation without external coprocessor. |
| Max Clock Rate | 100 MHz (1.3-V core supply) - delivers 200 MMACS throughput for computationally intensive audio preprocessing. |
| On-Chip Memory | 64KB DARAM + 128KB ROM - zero-wait-state execution of time-critical code and preloaded algorithms (e.g., speech codecs). |
| I/O Voltage Support | 1.8 V / 2.5 V / 2.75 V / 3.3 V - allows direct interfacing with diverse sensors, codecs, and memory without level-shifting circuitry. |
| Power Domains | Three isolated domains (ANA, RTC, peripherals) - enables selective power gating to reduce system standby current below 0.3 mW. |
| Peripheral Set | 4× I²S, 2× SD/eMMC, 1× UART, 1× SPI (4 CS), 1× I²C, 3× GP timers, RTC - sufficient for stereo audio streaming, sensor logging, and host communication. |
| Package | 144-pin Pb-free BGA (ZHH), 12 mm × 12 mm - compatible with high-density PCB layouts and automated assembly processes. |
Pinout & Package
144-terminal Pb-free plastic BGA (ZHH suffix), 12.0 mm × 12.0 mm body size, 0.8-mm ball pitch. Pinout validated per TI SPRS737C Figure 4-1 and Table 4-2 (pin function mapping confirmed for TMS320C5532 family).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CVDD | DSP Core Power Supply | 1.3-V input for 100-MHz operation; must be regulated within ±3% to ensure timing compliance. |
| DVDDIO | I/O Power Supply | Configurable 1.8/2.5/2.75/3.3-V rail; sets voltage level for all GPIO, I²S, SPI, and UART I/O buffers. |
| CLKIN / CLK_SEL | External Clock Input & Selection | Accepts crystal (RTC_XI/RTC_XO) or external oscillator; CLK_SEL configures source for internal PLL. |

Key Features
| Feature | Design Value |
|---|---|
| Dual-MAC Architecture | Two independent 17×17-bit multipliers + 40-bit accumulator enable simultaneous multiply-accumulate operations - critical for real-time adaptive filtering and noise suppression. |
| Four Independent DMA Controllers | 16-channel DMA subsystem moves data between peripherals and memory without CPU intervention - preserves 100% CPU bandwidth for algorithm execution. |
| Software-Programmable PLL | Configurable x4–x4099 multiplier allows precise clock generation from low-frequency crystals - simplifies board-level clock tree design and reduces BOM count. |
| Isolated Power Domains | ANA, RTC, and peripheral domains can be powered independently - enables deep-sleep modes where only RTC remains active (<0.3 mW system standby). |
| On-Chip Bootloader (RBL) | ROM-resident bootloader supports boot from SPI EEPROM, SPI flash, I²C EEPROM, SD/eMMC, UART, or USB - eliminates need for external boot PROM and accelerates firmware updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320C5534AZHH10 | Includes 192KB SARAM (vs. 0KB), USB 2.0 device PHY, and LCD bridge - larger memory and connectivity at higher power and cost. | Suitable when local display output or USB firmware updates are required; not drop-in due to different peripheral register map and power sequencing. | Select if system requires USB device enumeration or >64KB working memory for multi-algorithm concurrent execution. |
| TMS320C5517AZHHA12 | Higher-performance C55x variant with 128KB DARAM, 256KB SARAM, and enhanced DMA arbitration - but larger 168-pin BGA and no RTC integrated. | Better for complex multi-threaded audio pipelines; lacks RTC and dedicated ANA_LDO, requiring external real-time clock and power management IC. | Choose when algorithm complexity exceeds TMS320C5532AZHH10 memory capacity and RTC is implemented externally. |
Compared with TMS320C5534AZHH10 and TMS320C5517AZHHA12, the TMS320C5532AZHH10 offers the smallest footprint and lowest static power among C55x BGA variants - making it optimal for space-constrained, battery-powered endpoints where USB, LCD, or large RAM are unnecessary.

FAQ
What is the maximum operating frequency of the TMS320C5532AZHH10?
The TMS320C5532AZHH10 operates at up to 100 MHz when supplied with a 1.3-V core voltage (CVDD), delivering 200 million multiply-accumulates per second (MMACS). At 1.05 V, its maximum frequency is 50 MHz with 20-ns instruction cycle time - both configurations are supported and documented in TI's SPRS737C datasheet.
Does the TMS320C5532AZHH10 include an integrated ADC?
No, the TMS320C5532AZHH10 does not include an integrated SAR ADC. Unlike the TMS320C5535, it omits the 10-bit 4-input ADC entirely - requiring external analog-to-digital conversion for sensor or audio front-end applications. This omission reduces silicon area and static power, aligning with its role as a lean, low-cost DSP engine.
Can the TMS320C5532AZHH10 boot from SD card?
Yes, the TMS320C5532AZHH10 supports boot from SD/eMMC via its on-chip ROM bootloader (RBL), as confirmed in Section 1.1 and Table 6-1 of SPRS737C. The RBL initializes SD0/SD1 interfaces and loads executable code directly into internal DARAM, enabling field-upgradable firmware without external programming hardware.
What power supply domains are present on the TMS320C5532AZHH10?
The TMS320C5532AZHH10 implements three isolated power domains: ANA_LDO (1.3 V for PLL and analog circuits), RTC (separate supply for real-time clock), and peripherals (DVDDIO for I/O and interface logic). It does not include DSP_LDO or USB_LDO - confirming its simplified power architecture versus higher-tier C553x variants.
Is USB functionality available on the TMS320C5532AZHH10?
No, USB 2.0 device functionality is explicitly excluded from the TMS320C5532AZHH10. As shown in Table 3-5 and the functional block diagram, USB PHY, USB_LDO, and related pins (USB_DP, USB_DM, USB_VBUS) are absent - distinguishing it from TMS320C5535/C5534/C5533 and confirming its focus on minimal peripheral count and power efficiency.
