MPN Structure

Telink uses two naming conventions for their BLE and Zigbee SoCs:

Legacy TLSR Naming

CopyTLSR[SERIES][VARIANT][FEATURES][PACKAGE]
   |    |       |        |        |
   |    |       |        |        +-- Package code (ET32, ET48, Q)
   |    |       |        +-- Feature/flash suffix (F512, F1M)
   |    |       +-- Variant letter (A, B, etc.)
   |    +-- Series number (8251, 8258, 9218)
   +-- Telink Low-power Semiconductor Radio

Newer B-Series Naming

CopyB[SERIES][VARIANT]
  |   |      |
  |   |      +-- Variant (M for module, etc.)
  |   +-- Series number (85, 87, 91, 92)
  +-- B-series (BLE-focused)

Example Decoding

CopyTLSR8258F512ET32
|    |   |    |
|    |   |    +-- ET32 = QFN-32 package
|    |   +-- F512 = 512KB Flash
|    +-- 8258 = BLE 5.0 series
+-- TLSR = Telink Low-power Semiconductor Radio

B91M
| ||
| |+-- M = Module variant
| +-- 91 = RISC-V BLE 5.2 series
+-- B-series naming

Product Families

TLSR82xx Series (BLE 5.0)

TLSR825x Series (Zigbee 3.0)

TLSR92xx Series (BLE 5.2)

B-Series (Newer Naming)

Package Codes

Package Code Extraction

The handler looks for package codes in these locations:

1. After hyphen: TLSR8258-Q32
2. Embedded in suffix: TLSR8258ET32
3. Trailing digits: TLSR8258F51232 (32 = pin count)

Series Compatibility

Upgrade Paths

CopyTLSR8251 -> TLSR8258 (more features, pin-compatible)
TLSR8258 -> TLSR8269 (more Flash/features)
B85 -> B87 (improved BLE 5.0)
TLSR82xx -> TLSR92xx (BLE 5.0 to 5.2 upgrade)

Handler isOfficialReplacement() Logic

Copy// Compatible upgrades:
TLSR8258 can replace TLSR8251
TLSR8269 can replace TLSR8258
B87 can replace B85
TLSR92xx can replace TLSR82xx

Handler Implementation Notes

Series Extraction

Copy// TLSR series: extract first 8 alphanumeric characters
// TLSR8258F512ET32 -> TLSR8258

// B-series: extract B + 2 digits
// B91M -> B91

Package Code Extraction

Copy// Check for explicit package suffix patterns
// Format: TLSR8258F512ET32 where last digits indicate package

// Common patterns: ET32 (QFN-32), ET48 (QFN-48), ET24 (QFN-24)
if (upperMpn.matches(".*ET32.*") || upperMpn.endsWith("32")) {
    return "QFN-32";
}

Matching Logic

Both IC and MICROCONTROLLER component types are supported:

• TLSR series: ^TLSR[0-9]{4}.*
• B-series: ^B[0-9]{2}[A-Z]*.*

Learnings & Edge Cases

• Dual naming convention: Telink transitioned from TLSR to B-series naming. Both are still in use.
• BLE/Zigbee dual-mode: Some chips like TLSR8258 support both BLE and Zigbee protocols.
• Flash size in MPN: F512 = 512KB, F1M = 1MB - important for firmware sizing.
• Package in trailing digits: If MPN ends with 32/48/24, it indicates QFN pin count.
• B91 is RISC-V: Unlike older TLSR chips (ARM Cortex-M0), B91 uses RISC-V core.
