Beken Corporation Manufacturer Skill
Company Overview
Beken Corporation specializes in WiFi and Bluetooth Low Energy (BLE) System-on-Chip (SoC) solutions, primarily targeting IoT applications including smart home, audio, and wearable devices.
MPN Structure
Beken MPNs follow this general structure:
[PREFIX][SERIES][-PACKAGE]
| | |
| | +-- Optional: Package code (QFN-32, QFN-40)
| +-- Series number (7231, 3431, etc.)
+-- BK prefix (Beken)
Example Decoding
BK7231
| |||
| ||+-- 1 = Variant
| |+-- 3 = Submodel
| +-- 72 = WiFi + BLE series
+-- BK = Beken prefix
BK7231-QFN-32
| ||| | |
| ||| | +-- 32 = 32-pin
| ||| +-- QFN = Package type
| ||+-- 1 = Variant
| |+-- 3 = Submodel
| +-- 72 = WiFi + BLE series
+-- BK = Beken prefix
BK3432
| |||
| ||+-- 2 = BLE 5.0 variant
| |+-- 3 = Submodel
| +-- 34 = BLE-only series
+-- BK = Beken prefix
Series Overview
| Series | Wireless Type | Protocol | Application | |--------|---------------|----------|-------------| | BK7xxx | WiFi + BLE | WiFi 4/6 + BLE | Smart home, audio | | BK3xxx | BLE only | BLE 4.x/5.x | Wearables, sensors |

| Part Number | WiFi | BLE | Features | |-------------|------|-----|----------| | BK7231 | 802.11 b/g/n | BLE 4.2 | Basic combo | | BK7251 | 802.11 b/g/n | BLE 5.0 | Audio + WiFi | | BK7256 | 802.11ax (WiFi 6) | BLE 5.2 | Latest gen |
BK3xxx Series - BLE Only Chips
| Part Number | BLE Version | Features | |-------------|-------------|----------| | BK3431 | BLE 4.2 | Basic BLE | | BK3432 | BLE 5.0 | Enhanced range |
Package Codes
| Code | Package | Pin Count | Description | |------|---------|-----------|-------------| | QFN-32 | QFN | 32 | Quad Flat No-lead, 32-pin | | QFN-40 | QFN | 40 | Quad Flat No-lead, 40-pin | | QFN-48 | QFN | 48 | Quad Flat No-lead, 48-pin | | N | QFN | - | QFN (generic) | | Q | QFN | - | QFN (alternate code) |
Wireless Capabilities

| Feature | BK7231 | BK7251 | BK7256 | |---------|--------|--------|--------| | WiFi Standard | 802.11n | 802.11n | 802.11ax | | WiFi Band | 2.4GHz | 2.4GHz | 2.4GHz | | BLE Version | 4.2 | 5.0 | 5.2 | | Audio Support | No | Yes | Yes | | Target Market | Basic IoT | Audio IoT | Premium IoT |
BLE Only (BK3xxx)
| Feature | BK3431 | BK3432 | |---------|--------|--------| | BLE Version | 4.2 | 5.0 | | Range | Standard | Extended | | Power | Low | Ultra-low |
Handler Implementation Notes
Pattern Matching
// WiFi + BLE combo chips (BK7xxx series)
"^BK7[0-9]{3}.*"
// BLE only chips (BK3xxx series)
"^BK3[0-9]{3}.*"
// Combined matching in matches() method
if (type == ComponentType.IC) {
return upperMpn.matches("^BK7[0-9]{3}.*") ||
upperMpn.matches("^BK3[0-9]{3}.*");
}
Package Code Extraction
// Check for QFN-xx pattern (handles BK7231-QFN-32)
int qfnIndex = upperMpn.indexOf("QFN");
if (qfnIndex >= 0) {
// Extract from QFN including pin count
// Handle both QFN-32 and QFN32 formats
}
// Check suffix letters if no explicit QFN
if (suffix.startsWith("N") || suffix.startsWith("Q")) {
return "QFN";
}
Series Extraction
// Extract 6 characters for series (e.g., BK7231, BK3432)
if (upperMpn.matches("^BK7[0-9]{3}.*") ||
upperMpn.matches("^BK3[0-9]{3}.*")) {
return upperMpn.substring(0, 6);
}
Wireless Type Detection
// BK7xxx = WiFi + BLE
if (upperMpn.matches("^BK7[0-9]{3}.*")) {
if (upperMpn.startsWith("BK7256")) return "WIFI6_BLE5";
return "WIFI_BLE";
}
// BK3xxx = BLE only
if (upperMpn.matches("^BK3[0-9]{3}.*")) {
if (upperMpn.startsWith("BK3432")) return "BLE5";
return "BLE";
}
Replacement Compatibility
Same Series Replacements
Parts within the same series are compatible if:
- Same base series (BK7xxx or BK3xxx)
- Same or compatible package (QFN with matching pin count)
Cross-Series Restrictions
- BK7xxx (WiFi+BLE) cannot replace BK3xxx (BLE only) - different interfaces
- BK3xxx cannot replace BK7xxx - missing WiFi capability
Package Compatibility
// QFN packages with same pin count are compatible
// QFN-32 != QFN-40 (different pinouts)
// Unspecified package assumes compatible
Application Guidelines
| Use Case | Recommended Series | |----------|-------------------| | Smart home devices | BK7231, BK7256 | | Audio streaming | BK7251 | | Wearables | BK3431, BK3432 | | Low-power sensors | BK3432 | | WiFi 6 devices | BK7256 |
Development Ecosystem

Learnings & Edge Cases
- Series determines wireless: BK7xxx = WiFi+BLE, BK3xxx = BLE only
- Package in suffix or inline: Can appear as -QFN-32 or BK7231N
- Pin count critical: QFN-32 and QFN-40 are NOT compatible
- BK7256 special: Only WiFi 6 (802.11ax) capable chip
- Audio support varies: BK7251 has audio codec, BK7231 does not
- Tuya integration: Many BK7231 modules are Tuya-based IoT devices
- WiFi capability: Only BK7xxx series supports WiFi, all support BLE
