Hacking the Timex m851
Part of the magic is how bonkers frugal the Epson SoC (PN S1C88349) is: when running at a low-power mode at 32kHz, it consumes an astoundingly low 9 microamps. [1] How much do you think you could get done with a cycle budget of 32k per second?That, and alongside 48K ROM and 2K RAM, you get 3 timers, a UART, and an A/D converter.
