The A5191HRT is a single-chip CMOS modem designed for highway addressable remote transducer (HART) applications. It operates at a half-duplex mode with a data rate of 1200 bits per second using phase continuous frequency shift keying (FSK). The modem integrates essential functions such as modulation, demodulation, receive filtering, carrier detection, and transmit-signal shaping, requiring only a few external passive components. This device supports Bell 202 shift frequencies of 1200 Hz and 2200 Hz and operates within a power supply range of 3.0 V to 5.5 V, making it suitable for low-power applications, including intrinsically safe environments. The A5191HRT is compatible with both 3.3 V and 5 V microcontrollers and requires a 460.8 kHz crystal or ceramic resonator for its internal oscillator. The modem is rated for an industrial temperature range of -40¬8C to +85¬8C and is available in multiple package types, including 28-pin PLCC, 32-pin QFN, and 32-pin LQFP. It is also Pb-free, aligning with environmental standards. Applications for the A5191HRT include HART multiplexers, modem interfaces, and 4-20 mA loop-powered transmitters.
