1. Introduction
1.1 Scope
FIRECREST is the customer evaluation board for the S1V30120 Speech Synthesis IC.
The FIRECREST board provides the necessary clocking, power, configuration and interfaces to
allow evaluation of the S1V30120. It is designed to be used as a daughterboard to the S1V30100
Evaluation Board Nightingale, which provides a USB interface to a PC.
This user manual describes the FIRECREST board in detail.
1.2 Document Structure
The User Guide is structured as follows. Section 2 gives an overview of the FIRECREST board and
the major components and interfaces. Section 3 describes the board configuration options available
on FIRECREST. Section 4 describes each system component and interface in detail.

2. System Overview
FIRECREST provides the required clocks, power, configuration and interface connectors to allow evaluation
of the S1V30120 Silicon.
This section gives an overview of the main blocks and interfaces in the system. Section 2.1 provides an
overview of the major blocks on the FIRECREST board. Section 2.2 summarizes the main interfaces on
FIRECREST.
2.1 System Block Diagram
Figure 1 is a block diagram of the FIRECREST board that illustrates the main system components.
The clocking and system configuration options are also shown on the left-side of the figure.
FIRECREST implements a number of amplifier circuits for converting the S1V30120 headphone
output to a speaker output. Consult the BOM that is delivered with the evaluation kit for details of the
fitted components

3. Configuration Options
FIRECREST has a number of configuration options. Some options are selected using configuration switches
on the board.
3.1 Configuration Switches
FIRECREST has a DIP switch (SW5) for controlling configuration options. The table below
describes the function of each of this configuration switch, together with its default position.

4. Detailed Interface Descriptions
4.1 Power Supply
FIRECREST receives power from the J5 Connector when connected to the NIGHTINGALE board.
Two yellow LEDs are fitted which indicate whether power is being supplied to the 3.3V and 1.8V –
these are marked as 3.3V (LED1) and 1.8V (LED2) respectively on the board.
4.2 Clocks
FIRECREST requires only a single external clock of 32.768kHz for operation. The clock oscillator
Y1 on the board supplies this signal.
4.3 Reset
Switch SW7 allows the FIRECREST board to be reset. The reset is commoned with SYS_RESET on
the NIGHTINGALE board.
4. Detailed Interface Descriptions
4.4 SPI Interfaces
The S1V30120 has a single SPI Slave Interface. Table 3 shows the pin-out of the SPI Test Connector.
The SPI Slave Interface uses the signals SIN, SOUT, SCLK, SFRM1 for serial data in, serial data out,
serial clock, and slave select respectively.
The SPI test-connectors uses a 6-pin AMP MicroMatch Test connector.

4.5 GPIO Buttons
The S1V30120 firmware uses two GPIOs to communicate information to/from the host processor to
control STANDBY mode and indicate the availability of a message to be received from the
S1V30120. These can be controlled/observed on the FIRECREST board as shown in Table 4.

All the GPIO Port A signals of S1V30120 can be accessed via the 10-pin AMP MicroMatch test
connector (J1). Connector J1 is given below in Table 5.
