Core RF & Modem Specifications

• Frequency Band: Supports 868 MHz (Europe) and 915 MHz (North America) ISM bands, with flexible frequency tuning via an integrated PLL (Phase-Locked Loop) for precise channel selection.

• Transmit Power: Programmable output power up to +20 dBm (100 mW), enabling extended communication range (up to several kilometers in line-of-sight conditions) and strong penetration through obstacles in harsh industrial environments.

• Receiver Sensitivity: Industry-leading sensitivity of -124 dBm at 1.2 kbps data rate, ensuring reliable signal reception even with weak RF signals, minimizing packet loss and extending network coverage.

• Modulation Schemes: Supports multiple modulation formats including FSK (Frequency Shift Keying), GFSK (Gaussian Frequency Shift Keying), OOK (On-Off Keying), and MSK (Minimum Shift Keying), compatible with legacy and modern wireless protocols for broad interoperability.

• Data Rate: Configurable data rates from 1.2 kbps to 500 kbps, balancing range, latency, and throughput to match diverse application requirements (low-rate for long-range, high-rate for fast data transfer).

• RF Performance: Integrated low-noise amplifier (LNA), power amplifier (PA), and RF filters; supports frequency hopping spread spectrum (FHSS) for enhanced anti-interference, coexistence with other 868/915 MHz devices, and compliance with ETSI EN 300 220 and FCC Part 15.247 regulatory standards.

Integrated Microcontroller & Memory

• Core: Embedded 8051-compatible 8-bit microcontroller (MCU) running at up to 16 MHz, with a single-cycle instruction set for efficient real-time processing and protocol handling.

• Memory:

  • Flash Memory: 64 KB of on-chip non-volatile flash for storing application firmware, protocol stacks, and configuration data, supporting in-system programming (ISP) and in-application programming (IAP).

  • RAM: 4 KB of SRAM for data buffering, stack operations, and runtime variable storage, sufficient for typical IoT and industrial sensor node applications.

   

• Peripherals: Rich on-chip peripherals including 12-bit analog-to-digital converter (ADC, 8 channels), UART, SPI, I2C, PWM outputs, GPIO pins, watchdog timer, and low-power timers, enabling direct interfacing with sensors, actuators, displays, and external components without additional ICs.

Power Management & Low-Power Modes

• Supply Voltage: Wide operating voltage range of 2.0 V to 3.6 V, compatible with battery-powered (AA/AAA, Li-ion) and low-voltage embedded systems.

• Power Consumption: Ultra-low power design for battery longevity:

  • Receive Mode: ~12 mA (typical) at 3.3 V

  • Transmit Mode: ~85 mA (typical at +20 dBm, 3.3 V)

  • Sleep Mode: <1 µA (deep sleep, RAM retention), <0.1 µA (shutdown mode), supporting years of operation on coin-cell or AA batteries for battery-powered sensor nodes.

   

• Power Management: Integrated voltage regulator, power-on reset (POR), and brown-out detection (BOD) circuits for stable operation across voltage fluctuations and harsh environmental conditions.

Package & Application Focus

• Package: Available in a QFN-48 (7x7 mm) compact surface-mount package, ideal for space-constrained IoT devices, sensor nodes, and compact industrial modules.

• Target Applications:

  • Industrial IoT (IIoT): Wireless sensor networks, industrial automation, remote meter reading (electricity/gas/water), asset tracking.

  • Smart Home & Building Automation: Security alarms, wireless thermostats, lighting control, smoke detectors.

  • Agricultural Monitoring: Soil moisture, temperature, and environmental sensor networks.

  • Wireless Remote Controls: Industrial remote switches, medical devices, and low-power telemetry systems.
