California Eastern Labs ZIC2410 Chip and Module
In addition to modules built on a SNAP Engine footprint, you will find SNAP running on CEL chips
(ZIC2410) and modules (ZICM2410P0, without a power amplifier, and ZICM2410P2, with a power
amplifier). Versions with the power amplifier require SNAP firmware version 2.2.16 or higher. See
the following section for details unique to the SNAP Engine form factor.
The default setting for NV parameters is to assume that the power amplifier is available. Users running
on the original (non-PA) hardware will need to clear the “PA” Feature Bit (0x10). SNAP modules with
the hardware amplifier will be labeled ZICM2410P2, while those without the amplifier will be labeled
ZICM2410P0.
For example, if your feature bits are currently 0x1F, then a saveNvParam(11, 0x0F) will clear the
“PA” bit.
The following table summarizes the IO mapping on the ZIC2410 chip.

The same IO numbering scheme applies to the ZICM2410P0 and ZICM2410P2 modules, but be aware
that not all of the chip’s pins are brought out of the module. Specifically, P1.2 (IO 10) and P1.5 (IO
13) are not brought out, and so cannot be used in your module scripts. (You can use these pins if you
are running SNAP on the bare ZIC2410 chip.)
Additionally, P1.6 (IO 14) and P1.7 (IO 15) are available on the ZICM2410P0 modules, but are not
connected on the ZICM2410P2 modules, as they are used internally to control the power amplifier.
Separate Analog Input Pins
Unlike many of the SNAP platforms, the analog input pins on the ZIC2410 do not overlap any of the
digital IO or other peripherals. You still use the readAdc(channel) SNAPpy built-in to access the four
ACHx channels on the ZIC2410.
