For engineers reviewing the CC430F6137IRGCT datasheet, CC430F6137IRGCT pinout, CC430F6137IRGCT application, or CC430F6137IRGCT equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in AMR/AMI metering and smart grid networks, and confirmed alternative options aligned with TI's official device comparison table.

Technical Context

The CC430F6137IRGCT combines the MSP430 CPUXV2 core (16-bit RISC, up to 20-MHz system clock) with a CC1101-based RF transceiver supporting 0.6–500 kBaud data rates, FSK/GFSK/MSK/OOK modulation, and integrated packet handling including sync word detection, address check, CRC, and CCA. Its unified clock system includes FLL, SMCLK, ACLK, and RF-specific oscillators (RF_XIN/RF_XOUT).

It implements five low-power modes (LPM0–LPM4), achieving 1.0 µA in LPM4 (RAM retention) and 2.0 µA in LPM3 (RTC active), with wake-up from standby in under 6 µs. The analog subsystem includes a 12-bit ADC with internal reference, sample-and-hold, autoscan, and eight external analog inputs (A0–A7), plus comparator_B with eight channels.

FAQ

What is the maximum RF output power supported by the CC430F6137IRGCT?

The CC430F6137IRGCT supports programmable RF output power up to +12 dBm across all supported frequency bands (300–348 MHz, 389–464 MHz, 779–928 MHz). This is achieved using its integrated CC1101-based transceiver core and is configurable via register settings in the RF frontend. The CC430F6137IRGCT maintains this output level while meeting EN 300 220 and FCC Part 15 spectral mask requirements.

Does the CC430F6137IRGCT include hardware support for secure communication?

Yes, the CC430F6137IRGCT integrates a dedicated 128-bit AES encryption and decryption coprocessor. This hardware accelerator performs cryptographic operations independently of the CPU, enabling fast, low-power secure messaging for protocols such as DLMS/COSEM or custom encrypted telemetry. The CC430F6137IRGCT uses key storage and cipher mode configuration registers accessible via the peripheral module interface.

How many analog inputs does the 12-bit ADC on the CC430F6137IRGCT support?

The CC430F6137IRGCT features a 12-bit ADC (ADC12_A) with eight external analog input channels (A0 through A7), plus four internal sources (temperature sensor, supply voltage, VREF+/VeREF+, VREF−/VeREF−). These inputs are selectable via the ADC12MCTLx registers, and the module supports autoscan mode for sequential conversion of multiple channels without CPU intervention.

What LCD capabilities does the CC430F6137IRGCT provide?

The CC430F6137IRGCT includes an integrated LCD_B module supporting up to 96 segments with static, 2-, 3-, or 4-mux configurations. It drives common outputs (COM0–COM3) and segment lines (S0–S35, plus additional mapped pins), with built-in contrast control and charge pump. This eliminates the need for external LCD controllers in applications like thermostats and heat cost allocators.

What is the lowest active current consumption of the CC430F6137IRGCT in low-power mode?

The CC430F6137IRGCT achieves 1.0 µA in LPM4 (RAM retention, all clocks disabled), and 2.0 µA in LPM3 (RTC active with 32-kHz ACLK). These values are measured at 3-V supply and 25°C per TI's SLAS554I datasheet. The CC430F6137IRGCT maintains full RAM retention and fast wake-up (< 6 µs from LPM3), enabling multi-year battery operation in intermittent-sensing applications.
