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

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 |

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
