Texas Instruments CC430F5145IRGZT

Overview

CC430F5145IRGZT from Texas Instruments is an ultra-low-power System-on-Chip (SoC) integrating a 16-bit MSP430 CPU, sub-1 GHz RF transceiver (CC1101 core), 10-bit ADC with six external inputs, AES-128 security accelerator, and two USCI modules (UART/IrDA/SPI/I²C). It operates from 1.8 V to 3.6 V and delivers 160 µA/MHz active current, 2.0 µA LPM3 RTC mode, and 15 mA RX current at 915 MHz - enabling battery-powered wireless sensor nodes for smart metering and industrial telemetry.

For engineers reviewing the CC430F5145IRGZT datasheet, CC430F5145IRGZT pinout, CC430F5145IRGZT application, or CC430F5145IRGZT equivalent, key selection criteria include RF frequency band support (300–928 MHz), integrated radio coexistence with MCU peripherals, low-power sleep modes (LPM3.5/LPM4.5), and verified EN 300 220 / FCC Part 15 compliance - all critical for certified wireless endpoint design.

Technical Context

The CC430F5145IRGZT implements a tightly coupled SoC architecture where the MSP430XV2 CPU shares memory space and DMA channels with the CC1101-based RF subsystem, enabling zero-copy packet handling and deterministic interrupt latency. Its unified clock system uses an FLL with internal REFO and external XT1/XT2 oscillators to synchronize MCU timing and RF modulation clocks.

RF operation is managed via dedicated registers in the RF1A peripheral, supporting programmable data rates (0.6–500 kBaud), digital RSSI, automatic CRC, sync word detection, and CCA for listen-before-talk protocols - all accessible through memory-mapped I/O without host CPU intervention during packet reception/transmission.

FAQ

What is the maximum RF output power supported by the CC430F5145IRGZT?

The CC430F5145IRGZT supports programmable RF output power up to +12 dBm across all supported frequency bands (300–348 MHz, 389–464 MHz, 779–928 MHz). This value is achieved using the integrated CC1101 RF core's PATABLE register configuration and is verified per TI's SLAS555B datasheet Section 5.62. The CC430F5145IRGZT maintains this output level while operating within its 1.8–3.6 V supply range and specified temperature limits.

Does the CC430F5145IRGZT include hardware AES encryption?

Yes, the CC430F5145IRGZT integrates a dedicated 128-bit AES security coprocessor that performs encryption and decryption in hardware. This accelerator operates independently of the MSP430 CPU, enabling secure over-the-air firmware updates and encrypted sensor data transmission without compromising real-time performance. The CC430F5145IRGZT's AES engine is documented in Section 1.1 Features and Section 6.11 Peripherals of the SLAS555B datasheet.

What are the low-power sleep modes available on the CC430F5145IRGZT?

The CC430F5145IRGZT supports seven low-power modes including LPM3.5 (RTC-only, 1.0 µA) and LPM4.5 (shutdown, 0.3 µA), as specified in Section 1.1 Features and Section 5.6 of the SLAS555B datasheet. These modes retain calendar functionality and RAM content while minimizing current draw - critical for multi-year battery life in wireless endpoint applications such as AMR meters and heat cost allocators using the CC430F5145IRGZT.

Which frequency bands does the CC430F5145IRGZT support for RF communication?

The CC430F5145IRGZT supports three licensed and license-free sub-1 GHz frequency bands: 300–348 MHz, 389–464 MHz, and 779–928 MHz. These bands enable compliance with regional regulations including EN 300 220 (Europe) and FCC CFR Part 15 (US), as well as Wireless M-Bus EN 13757-4:2005. The CC430F5145IRGZT's RF core is identical to the CC1101 transceiver, and band selection is configured via register settings per Section 5.43 of the datasheet.

How many analog inputs does the 10-bit ADC on the CC430F5145IRGZT support?

The CC430F5145IRGZT features a 10-bit ADC (ADC10_A) with six external analog input channels plus two internal sensors (temperature and supply voltage), as confirmed in Table 3-1 (Device Comparison) and Section 1.1 Features of the SLAS555B datasheet. This configuration supports direct connection of multiple analog sensors without external multiplexing, distinguishing it from the CC430F614x series which offers eight external inputs.
