Specifications

Panasonic PAN4561 (SNAP Engine Form Factor)
The PAN4561 utilizes the same core processor as the original RFE and PAN4555 (the Freescale
HCS08). In fact, the PAN4561 utilizes the same MC13213 integrated IC (HCS08 plus radio front end)
as the PAN4555.
As such, the PAN4561 will use a firmware version designed for all modules based on the Freescale
MC1321x series of chipsets. This same firmware will run on the PAN4555, PAN4561, etc.
The version of SNAP software developed for the PAN4561 follows the same GPIO structure of the
PAN4555 for the first 18 GPIO pins.
However, there are a few functional details to be aware of:
Increased Number of GPIO Pins
The PAN4561 has a total of 33 available GPIO pins. These include:
• 8 Analog-to-Digital (ADC) pins
• UARTs
• 8 Keyboard Interrupt pins (KBI)
• Pulse-Width Modulated (PWM) output pins
Platform Specific Settings
SNAPpy NV-Param #41 is used to store the platform name. For this module the name is ‘PAN4561’.
This value can be modified by the user. However, this has the potential to affect SNAPpy script
functionality. The platform name will normally be set during the initial programming of the module at
the factory.
SNAPpy NV-Param #63 stores the trim value for the radio transceiver’s crystal oscillator (not to be
confused with the separate trim value related to the HCS08 MCU). If this value is not set, then the
radio will be configured to use the default value- typically 0x7E (see MC1321x reference manual for
details). The trim value will be set during the initial programming of the module at the factory.
SNAP feature bits are used to control a number of things, including module specific settings. For the
PAN4561 mounted onto a SNAPpy Engine carrier, a feature bit has be used to specify that a power
amplifier exists and that this PA will be disabled before the module enters into a sleep state (and re-
enabled upon waking). The 6
th
bit (0x20) of Non-Volatile Parameter (NV-Param) #11 is used to store
this particular setting. The appropriate feature bits will be set during initial programming at the
factory. This setting has no effect unless the module is mounted on a SNAP Engine carrier board or
Pin 52 and 45 are tied together (See following section for details).
None of these values will be reset when executing the ‘Factory Default NV Params’ menu option
within the Portal software.
