PRELIMINARY DATASHEET
The structure of the GPIO pads is shown in Figure 6-1. Configuration registers allow the user to
control pull-up and pull down resistors, enable the pin as an output or set the output value. See
ISD2360 Design Guide for details on the configuration options.
6.4 OSCILLATOR AND SAMPLE RATES
The ISD2360 has an internal oscillator trimmed at manufacturing that requires no external components
to operate. This oscillator provides an internal clock source that operates the ISD2360 at a maximum
audio sample rate
of 32kHz. The sample rates available for audio storage at this maximum
sample rate are shown in Table 6-1. The sample rate is selected during compression using the
ISD2360 Voice Prompt Editor software.

7 MEMORY FORMAT
The memory of the ISD2360 consists of byte addressable flash memory that is erasable in 1Kbyte
sectors. Erased memory has a value of 0xFF. Writing to the memory allows host to change bits from
erased ‘1’ state to programmed ‘0’ state.
The memory of the ISD2360 is organized into four distinct regions as shown in Figure 7-1. The four
regions are:
1. Configuration and Index Table: The first region of memory contains configuration data for
the device and the index table that points to the Voice Prompt and Voice Macro data. The
ISD2360VPE creates this section for download to the device.
2. Voice Macros: This section contains the script code of all the projects Voice Macros.
3. Voice Prompts: This section contains the compressed audio data for all Voice Prompts.
4. User Data: An optional section containing memory sectors allocated by the developer for
generic use by the host controller.
