Product Specifications
STM8L151G4U6TR — 16 KB Flash STM8L MCU, Tape & Reel for High-Volume Micro-Drone Sensor and BMS Production
The STM8L151G4U6TR is the tape-and-reel packaging variant of the STM8L151G4U6 — providing the same 16 KB Flash, 2 KB SRAM, 1 KB EEPROM, DMA controller, 12-bit ADC/DAC, and 0.35 µA Halt mode in a UFQFPN-28 (4×4 mm) package — but shipped in embossed carrier tape on a 13-inch reel (3,000 pcs/reel) for automated SMT assembly. This is the production ordering code for high-volume micro-drone BMS boards, wireless sensor tags, and wearable drone companion devices.

Product Overview
The STM8L151G4U6TR is the production-ready tape-and-reel variant for high-volume manufacturing of micro-drone BMS, wireless sensor tags, and wearable companion devices. Electrically identical to the tray-packaged STM8L151G4U6, the TR suffix indicates 3,000 units per 13-inch reel in embossed carrier tape suitable for automated pick-and-place machines. For drone manufacturers producing micro-BMS boards or sensor modules at scale, this is the standard ordering format that ensures uninterrupted SMT line feeding.
Key Features & Benefits
Identical Silicon — Zero Requalification
The TR variant uses the exact same UFQFPN-28 silicon as the tray variant. No firmware, timing, or electrical changes needed — only the pick-and-place feeder configuration changes when switching from prototype (tray) to production (TR).
3,000 Units Per Reel — Optimized QFN SMT Throughput
QFN packages have shorter placement times than leaded packages, and the 3,000-unit reel maximizes CPH (Components Per Hour) by minimizing reel changes. For micro-BMS boards with one L151 per board, one reel = 3,000 complete assemblies.
EMS-Ready Dry-Pack — MSL-3 with Humidity Indicator
Ships in sealed moisture-barrier bags per J-STD-033B with desiccant and HIC. UFQFPN-28 has MSL-3 rating with 168-hour floor life at ≤30°C/60% RH after opening — standard for QFN packages and well-supported by all contract manufacturers.
Target Applications
High-Volume Micro-Drone BMS Production
The default ordering code for manufacturers producing thousands of 2S–3S micro-BMS boards monthly. The TR format feeds directly into QFN-capable pick-and-place machines for high-speed, unsupervised assembly.
Mass-Produced Wireless Sensor Tags
For consumer-products companies building BLE sensor tags at 10K+ monthly volumes, the TR variant enables seamless SMT line integration with minimal operator intervention.
Frequently Asked Questions
Is the TR variant electrically different from the tray variant?
No. The die, package, test spec, and performance are identical. Only the shipping medium differs.
What is the reel quantity for UFQFPN-28 TR?
Standard reel quantity is 3,000 units on a 13-inch (330 mm) reel with 12 mm wide embossed carrier tape and 8 mm pitch. Detailed reel dimensions and leader/trailer specs are in the datasheet's package mechanical section.
