Telink Semiconductor Manufacturer Skill
MPN Structure
Telink uses two naming conventions for their BLE and Zigbee SoCs:
Legacy TLSR Naming
code
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
code
B[SERIES][VARIANT] | | | | | +-- Variant (M for module, etc.) | +-- Series number (85, 87, 91, 92) +-- B-series (BLE-focused)

Package Code Extraction
The handler looks for package codes in these locations:
- •After hyphen:
TLSR8258-Q32 - •Embedded in suffix:
TLSR8258ET32 - •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
code
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
java
// Compatible upgrades: TLSR8258 can replace TLSR8251 TLSR8269 can replace TLSR8258 B87 can replace B85 TLSR92xx can replace TLSR82xx
Handler Implementation Notes
Series Extraction
java
// TLSR series: extract first 8 alphanumeric characters // TLSR8258F512ET32 -> TLSR8258 // B-series: extract B + 2 digits // B91M -> B91
Package Code Extraction
java
// 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]*.*

Applications
- •Bluetooth Low Energy (BLE) devices
- •Zigbee 3.0 smart home devices
- •Thread/Matter IoT devices
- •BLE beacons and sensors
- •Wireless keyboards/mice
- •Audio devices (TWS earbuds)
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.
