Applies to: Trizeps IV(M), Trizeps IV WL, Trizeps V.

The Board Support Packages (Microsoft) for our Trizeps-modules support different realtime-clocks; i.e.
PCF8563 same chip as EPSON RTC-8564 (recommended)
PCF8563
M41T81
DS1340
DS1629
(see BSP for details of supported clocks) Of course support for other realtime-clocks can be added.

Signals
Most clocks use the I2C interface. Allthough the Trizeps already has pull-ups on these signals, designing additional pull-ups on the baseboard is recommended.
Signal-Name | SODIMM-Pin | Remark |
|---|---|---|
I2C_CLK | 196 | I2C-Clock-Signal (3,3V!) |
I2C_DATA | 194 | I2C-Data-Signal (3,3V!) |
