Product details
Overview
TC32306FTG from Toshiba is a single-chip UHF RF transceiver IC supporting ASK/FSK modulation across 315, 434, 868/915 MHz bands. It integrates LNA, mixer, IF filter (320 kHz / 270 kHz), RSSI detector, PLL/VCO, PA, and serial SPI/EEPROM control - enabling compact remote keyless entry and TPMS designs with ≤12 mA TX and 9.7 mA RX current consumption.
For engineers reviewing the TC32306FTG datasheet, TC32306FTG pinout, TC32306FTG application, or TC32306FTG equivalent, this page delivers verified functional block mapping, voltage-mode configuration logic (3V/5V selector pin), real-world receiver sensitivity (−116 dBm at 600 bps), antenna switch timing behavior, and confirmed alternative transceivers for RKE/TPMS system redesigns.
Technical Context
The TC32306FTG implements a single-conversion superheterodyne architecture with fractional-N PLL synthesizing local oscillator frequencies from a fixed 30.32 MHz crystal reference. Its dual IF filter bandwidths (320 kHz wide / 270 kHz mid) are selectable via register configuration to optimize noise immunity versus data rate in ASK/FSK demodulation.
Control is implemented via two distinct modes: SPI slave mode (MCU-driven register writes) and EEPROM master mode (autonomous boot-time configuration loading). Pin functions such as TX_SW/RX_SW, ENB, and MODE1/MODE2 dynamically reconfigure based on mode selection - with strict voltage domain isolation between analog (A_VDD_3V/A_VDD_5V), digital (D_REG), PLL (PLL_REG), and I/O (COM_VDD) supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si4362-B1B-FMR | Sub-GHz transceiver with integrated DC-DC converter; supports OOK/FSK; −133 dBm sensitivity; 20-pin QFN | Higher sensitivity and integrated power management; requires different layout and register map | Preferred when extending range beyond 20 m or powering from single 1.8–3.6 V supply without external LDO |
| AX5043-DQ63 | Sub-GHz transceiver with embedded packet handler; supports GFSK/MSK; −120 dBm sensitivity; 32-pin QFN | On-chip packet encoding/decoding and CRC; larger footprint and higher BOM cost | Chosen when offloading MCU packet framing tasks or requiring certified wireless stack compatibility |
Compared with TC32306FTG, Si4362-B1B-FMR offers superior sensitivity and integrated power conversion but lacks EEPROM boot autonomy; AX5043-DQ63 adds packet intelligence at the cost of increased design complexity and footprint - making TC32306FTG optimal for cost-sensitive, MCU-coordinated RKE/TPMS where simplicity and proven field reliability are prioritized.

FAQ
What is the maximum output power of the TC32306FTG and under what conditions is it achieved?
The TC32306FTG achieves +10 dBm typical transmit output power when configured for maximum PA drive level and operating at 315/434/868/915 MHz bands with proper impedance matching to A_VDD_3V. This value is measured at the RF_OUT pin under 3V or 5V supply, with the PA enabled and all internal regulators stabilized - meeting regulatory limits for short-range ISM band devices without external amplification.
How does the TC32306FTG handle supply voltage selection between 3V and 5V operation?
TC32306FTG uses the dedicated 3V/5V pin to configure internal voltage domains: grounding this pin selects 3V mode (all supplies tied to 3V), while connecting it to 5V enables internal A_REG30 regulation to generate 3V for analog blocks (LNA/PA) from the 5V rail. The pin must never exceed COM_VDD voltage to avoid ESD protection latch-up - and A_VDD_3V must not be externally driven in 5V mode.
Can the TC32306FTG operate without an external microcontroller?
Yes - in EEPROM Mode, TC32306FTG boots autonomously by reading configuration registers from an external SPI EEPROM upon RESET release. No MCU is required for basic transmit/receive operation, as all RF parameters, modulation settings, and timing are preloaded. This mode is ideal for ultra-low-cost beacons or factory-programmed sensors where MCU integration adds unnecessary cost and complexity.
What are the supported IF filter bandwidths and how are they selected on the TC32306FTG?
The TC32306FTG supports two IF filter bandwidths: 320 kHz (wide) and 270 kHz (mid), optimized for different data rates and adjacent-channel rejection needs. Selection is performed via register bits h'0A[D5:D4], not hardware pins - allowing dynamic reconfiguration during runtime. The wide setting improves timing margin for low-rate ASK signals; the mid setting enhances selectivity in dense RF environments.
Does the TC32306FTG include built-in signal detection logic, and how is it used?
Yes - TC32306FTG integrates configurable signal detection combining RSSI, noise, and preamble detection. Outputs DET_out (signal present) and Un_DET_out (no signal) are available on DET_TMONI1/2 pins and can be latched or updated continuously via h'10[D2]. This logic replaces external comparators and timers in RKE/TPMS receivers, reducing component count and improving detection consistency across temperature and voltage variation.
