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:

Copy[PREFIX][SERIES][-PACKAGE]
   |       |        |
   |       |        +-- Optional: Package code (QFN-32, QFN-40)
   |       +-- Series number (7231, 3431, etc.)
   +-- BK prefix (Beken)

Example Decoding

CopyBK7231
|  |||
|  ||+-- 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

Copy// 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

Copy// 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

Copy// 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

Copy// 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:

1. Same base series (BK7xxx or BK3xxx)
2. 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

Copy// QFN packages with same pin count are compatible
// QFN-32 != QFN-40 (different pinouts)
// Unspecified package assumes compatible

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
