Parallax, Inc. • Emic Text-To-Speech Module (#30006) • 02/2005
Function
System power, +5V DC input.
Busy notification line. Digital logic HIGH when Emic Platform is in-use
(e.g., receiving characters, converting text-to-speech, etc.) or when a
system error has occurred. Logic LOW when the Emic Platform is idle
and ready to receive new commands or text. The visible LED on the
Emic Platform is red when BUSY is HIGH and green when BUSY is
LOW.
Serial In. TTL-level interface, 2400bps, 8 data bits, no parity, 1 stop bit.
Serial Out. TTL-level interface, 2400bps, 8 data bits, no parity, 1 stop
bit.
System ground. Connect to power supply’s ground (GND) terminal.
External system reset pin. Active LOW digital input. Bring this pin LOW
to reset the Emic Platform. Recommended use is after the host
controller power-up or an Emic Platform system error. This pin should
be left floating if it is not used.
Audio output buffer pin provides a single-ended analog output of the
synthesized speech for external amplification. Drives a minimum load of
5k Ω up to a maximum of 1Vp-p. The AC signal is superimposed on
approximately 1.2VDC bias and must be capacitively coupled to the
load.
Differential negative speaker driver output. Designed to drive an 8 Ω
speaker up to a maximum of 23.5mW for the OEM version and 300mW
for the SIP version. Do NOT connect this pin if using SP+ as single-
ended output (OEM version only).
Differential positive speaker driver output. Designed to drive an 8 Ω
speaker up to a maximum of 23.5mW for the OEM version and 300mW
for the SIP version. On the OEM version, this pin is biased to
approximately 1.2VDC and can be used as a single-ended output if
capacitively coupled to the load.
Analog input pin for SIP version only. Allows an audio signal to be fed
through the Emic Platform to either the AOUT or SP+/SP- pins. The
input has a nominal 694mVp-p level. There is no gain control on this
signal. The audio signal must be AC coupled to the AIN pin. No signal
should be active on the AIN pin when it is not in use, or else the signal
may bleed through to the Emic Platform's audio output at undesirable
times. This pin should be left floating if it is not implemented.
