Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD | power_in | Supply voltage input. Recommended operating range 1.8 V to 5.5 V; absolute maximum 6.0 V. Typical supply current is 35 nA at 2.5 V in operation mode. |+| 2 | GND | power_in | Device ground reference. |+| 3 | DELAY/M_RST | input | Dual-function pin: (1) Time-interval selection - a resistor REXT (500 Ω to 170 kΩ) between this pin and GND sets the WAKE interval, converted once after POR. (2) Manual reset - momentarily pulling this pin high to VDD (≥20 ms; VIH ≥ 1.5 V) triggers a manual reset (RSTn assertion). The reset switch is also connected to this pin. |+| 4 | DONE | input | Watchdog acknowledge input. Digital signal driven by the µC (low-to-high transition) to indicate successful processing of the WAKE signal. Must be asserted at least 20 ms before the next WAKE rising edge or the TPL5010 will assert RSTn. VIH = 0.7×VDD, VIL = 0.3×VDD. |+| 5 | WAKE | output | Timer output signal (push-pull). Digital pulsed output generated every tP period to wake the µC at the end of the programmed time interval. Pulse width typically 20 ms. Normally low. VOH ≥ VDD-0.3 at 100 µA, VOL ≤ 0.3 V at 100 µA. |+| 6 | RSTn | output | Reset output to the µC (open-drain, active low). Requires an external pull-up resistor (100 kΩ recommended to minimize current). Asserted low if DONE is not received in time, on manual reset, or during POR/REXT reading. Pulse width typically 320 ms. VOL ≤ 0.3 V at -1 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | RTC |+| Pins | 6 |++## Ordering variants++- `TPL5010DDCT`+- `TPL5010DDCTDDCR`++## CAD (KiCad official)++- Symbol: `TPL5010DDCT`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tpl5010ddct.pdf) (24 pp, sha256 `bc420f3ae10fe9a6`, retrieved 2026-08-17, tier: manufacturer)+- **Datasheet language:** Chinese.
