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
Product Families
TLSR82xx Series (BLE 5.0)
| Part | Description | Flash | Packages | |------|-------------|-------|----------| | TLSR8251 | BLE 5.0 SoC, entry-level | 512KB | QFN-32 | | TLSR8253 | BLE 5.0 SoC, mid-range | 512KB | QFN-32 | | TLSR8258 | BLE 5.0 SoC, feature-rich | 512KB/1MB | QFN-32, QFN-48 | | TLSR8261 | BLE 5.0/Mesh SoC | 512KB | QFN-32 | | TLSR8269 | BLE 5.0 high-end | 1MB | QFN-48 |
TLSR825x Series (Zigbee 3.0)
| Part | Description | Protocol | |------|-------------|----------| | TLSR8258 | Zigbee 3.0 + BLE dual-mode | Zigbee 3.0/BLE 5.0 | | TLSR8278 | Matter-ready SoC | Zigbee/Thread/BLE |
TLSR92xx Series (BLE 5.2)
| Part | Description | Features | |------|-------------|----------| | TLSR9218 | BLE 5.2 SoC | LE Audio, Direction Finding |
B-Series (Newer Naming)
| Part | Description | Core | |------|-------------|------| | B85 | BLE 5.0 | ARM Cortex-M0 | | B87 | BLE 5.0+ | ARM Cortex-M0 | | B91 | BLE 5.2 RISC-V | RISC-V | | B92 | BLE 5.3 RISC-V | RISC-V |
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:
- 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
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]*.*

Common MPNs
| MPN | Description | Package | |-----|-------------|---------| | TLSR8251F512ET32 | BLE 5.0, 512KB, QFN-32 | QFN-32 | | TLSR8258F512ET32 | BLE 5.0, 512KB, QFN-32 | QFN-32 | | TLSR8258F1MET48 | BLE 5.0, 1MB, QFN-48 | QFN-48 | | TLSR8269F1M | BLE 5.0 high-end, 1MB | Various | | TLSR9218 | BLE 5.2 | Various | | B91 | RISC-V BLE 5.2 | Various |
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.
