Product Description
1.1 Overview
The TDA7255V is an ASK/FSK single-channel transceiver for 433 - 435 MHz frequency band in a tiny VQFN-40 package. Due to the very high level of integration the device requires only a few external components. The extreme low current consumption in receive, transmit and especially in power down mode and the wide supply voltage range make TDA7255V the ideal choice for small, battery driven applications.
1.2 Features
• FSK and ASK modulation and demodulation capability without external circuitry changes, FM demodulation capability
• Frequency range: 433 to 435 MHz
• Sensitivity FSK typically -115 dBm at 4 kbit/s data rate
• Sensitivity ASK typically -112 dBm at 4 kbit/s data rate
• Transmit power up to +13 dBm
• Low supply current (Is = 9 mA typ. in receive mode, Is = 13,5 mA typ. in transmit mode (both at 3 V supply voltage, 25°C)
• Very low supply current in power down mode (5 nA typ.)
• Supply voltage range: 2.1 V to 5.5 V
• Data rates up to 100 kbit/s Manchester encoded
• Fully integrated PLL synthesizer including VCO and loop filter on-chip with on-chip crystal oscillator tuning
• Differential receive signal path completely on-chip, therefore no external filters are necessary
• On-chip low pass channel select and data filter with tuneable bandwidth
• Data slicer with self-adjusting threshold and 2 peak detectors
• Self-polling logic with adjustable duty cycle and ultrafast data rate detection and timer mode providing periodical interrupt
• Adjustable LNA gain
• Digital RSSI and battery voltage readout
• Clock Out Pin for external microcontroller
• I2C/3-wire microcontroller interface, working at max. 400 kbit/s
• Operating temperature range -40°C to +85°C
• 5.5 x 6.5 mm small VQFN-40 package
1.3 Application
The TDA7255V is targeted specifically at highly size-sensitive industrial and consumer applications such as small home automation or security and alarm systems.
Main applications:
• Bi-directional remote control systems
• Home automation systems
• Lighting control
• Security and alarm systems
• Industrial control
• Remote keyless entry systems
• Low bit-rate communication systems
