BC2502A/BC2502B

Sub-1GHz Low-IF FSK RF Receiver

Features

General Description

• Frequency bands

The BC2502x receiver devices adopt a fully-

integrated, low-IF FSK receiver with an automatic

gain control (AGC) function and a fully-integrated

FSK demodulator. The synthesizer is formed by an

integrated VCO and a fractional-N PLL to support the

315, 433, 868, and 915MHz frequency bands. The

devices only require a crystal and a minimum number

of passive components to fully implement a FSK

receiver. With this high level of functional integration,

these devices provide excellent solutions for low-cost,

low power wireless applications.

♦

BC2502A: 315MHz, 433MHz

♦

BC2502B: 315MHz, 433MHz,

868MHz, 915MHz

• Operating voltage range: 2.4V~5.5V

• 0.5µA deep sleep current with data retention

• Low RX current

♦

4.5mA @ 433MHz

♦

5.8mA @ 868MHz

• Supports FSK modulation

The devices achieve -112dBm sensitivity for the

433.92MHz bands. They operate from a supply

voltage of 2.4V to 5.5V and typically require 4.5mA

at 433.92MHz. There are two operation modes, one of

which is the Auto RX mode. By properly setting certain

PCB wirings, they can directly enter the RX mode. The

devices also support a sniff RX mode, where the on/

oﬀ RX mode function can be controlled by an MCU to

achieve a lower than average power consumption using

duty RX mode operation.

♦

FSK support up to 50Ksps symbol rate

• Good reception sensitivity under 0.1% BER

(BW=93.6k)

♦

-108dBm @ 25Kbps, 433MHz

• Wide RF input power range: from sensitivity to

+10dBm

• Support 2-wire I²C interface for operation

conﬁguration

The BC2502 series oﬀers two types of ICs. One is the

BC2502A which covers the 315 and 433MHz bands

while the BC2502B oﬀers a choice of four frequency

bands.

• On-chip VCO and Fractional-N synthesizer with

integrated loop ﬁlter

• Supports low cost 16MHz crystal

• FCC/ETSI Compliant

• Package type: 10-pin SOP-EP
