Key Parameters

Substitute Part Grouping Explanation

Substitution of the BLE112-A-V1 is determined by the following critical parameters:

RF Compatibility: Both the main part and substitute must operate in the Bluetooth standard at 2.4GHz frequency band to maintain wireless protocol compatibility.

Serial Interface Support: The substitute must provide SPI and UART interfaces to ensure compatibility with existing host microcontroller connections.

Antenna Configuration: Both parts utilize integrated chip antennas, eliminating external antenna redesign requirements.

Mounting and Package: Surface mount technology and module-level packaging must be maintained for PCB integration compatibility.

Supply Voltage Range: The substitute voltage range must overlap with or encompass the original 2V ~ 3.6V specification to support existing power supply designs.

Operating Temperature: The substitute must support the -40°C ~ 85°C operating range for equivalent environmental performance.

Compliance Standards: RoHS compliance status ensures regulatory alignment for production and distribution.

The BGM220PC22WGA2R qualifies as a manufacturer-recommended substitute based on these criteria, offering enhanced Bluetooth v5.2 protocol support while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

The BGM220PC22WGA2R is the manufacturer-recommended substitute for the obsolete BLE112-A-V1. Selection is justified on the following engineering grounds:

Protocol Compatibility: Bluetooth v5.2 maintains backward compatibility with Bluetooth v4.0, ensuring existing communication protocols function without modification.

Electrical Compatibility: The substitute voltage supply range (1.8V ~ 3.8V) encompasses the original specification (2V ~ 3.6V), permitting direct integration into existing power supply designs.

Interface Compatibility: The substitute retains SPI and UART interfaces required by the original design while offering additional serial interface options (I2C, I2S, PWM, USART, IrDA, ADC) for enhanced functionality.

Mechanical Compatibility: Both parts utilize surface mount technology and module-level packaging, maintaining PCB integration compatibility. Physical footprint verification is required prior to implementation.

Regulatory Compliance: Both parts meet RoHS standards. The substitute achieves ROHS3 compliance, representing current regulatory alignment.

Performance Enhancement: The substitute demonstrates improved receiver sensitivity (-98.9dBm vs. -85dBm), higher output power (8dBm vs. 3dBm), and substantially reduced power consumption (4.3mA ~ 4.8mA receiving vs. 25mA; 4.8mA ~ 10.8mA transmitting vs. 36mA).

Production Availability: The substitute is in active production status with current inventory, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the BGM220PC22WGA2R directly replace the BLE112-A-V1 without firmware changes?

A: The BGM220PC22WGA2R maintains Bluetooth v4.0 compatibility through v5.2 backward compatibility. Existing firmware designed for v4.0 operation will function on the v5.2 module. However, host microcontroller firmware may require updates to accommodate the substitute's additional serial interfaces and enhanced memory capacity if these features are utilized.

Q: What is the primary reason for substitution?

A: The BLE112-A-V1 is obsolete and no longer in production. The BGM220PC22WGA2R is the manufacturer-recommended active substitute that maintains electrical and mechanical compatibility while offering enhanced performance characteristics.

Q: Are the module packages physically compatible?

A: Both parts are surface mount modules. The BLE112-A-V1 uses a Module package, while the BGM220PC22WGA2R uses a 31-SMD Module package. Physical footprint, pin configuration, and PCB layout compatibility must be verified against manufacturer datasheets prior to implementation.

Q: What are the power consumption differences?

A: The BGM220PC22WGA2R demonstrates significantly lower power consumption: receiving current is reduced from 25mA to 4.3mA ~ 4.8mA, and transmitting current is reduced from 36mA to 4.8mA ~ 10.8mA. This improvement benefits battery-powered applications and reduces thermal management requirements.

Q: Does the substitute support the same serial interfaces?

A: The substitute supports all original interfaces (SPI, UART) plus additional options (I2C, I2S, PWM, USART, IrDA, ADC). Existing SPI and UART connections will function without modification.

Q: What is the voltage supply compatibility?

A: The substitute voltage range (1.8V ~ 3.8V) encompasses the original specification (2V ~ 3.6V). Existing power supply designs operating within the original range will function with the substitute.

Q: Are there memory differences?

A: The BGM220PC22WGA2R provides 352kB Flash and 32kB RAM compared to the BLE112-A-V1's 128kB Flash and 8kB SRAM. The increased memory capacity supports more complex firmware implementations and larger application code.

Q: What certifications apply to the substitute?

A: The BGM220PC22WGA2R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for component manufacturing and distribution.
