Telink Semiconductor Manufacturer Skill

MPN Structure

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

Legacy TLSR Naming

TLSR[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

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

Example Decoding

TLSR8258F512ET32
|    |   |    |
|    |   |    +-- 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

Package Codes

Code/Suffix	Package	Pin Count
ET32	QFN	32
ET48	QFN	48
ET24	QFN	24
Q32, QFN32	QFN	32
Q48, QFN48	QFN	48
Q	QFN	Various

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)

Feature Suffixes

Suffix	Meaning
F512	512KB Flash
F1M	1MB Flash
A, B	Silicon revision
M	Module variant

Series Compatibility

Upgrade Paths

TLSR8251 -> 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

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

Handler Implementation Notes

Series Extraction

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

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

Package Code Extraction

// 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.
