One Channel Speech Controller

5. FUNCTION DESCRIPTIONS

5.1 Oscillator

SNC26060P accepts RC type oscillator for system clock. The typical circuit diagram

for oscillator is listed as follows.

VCC

OSC

RC Oscillator

5.2 ROM

SNC26060P contains a substantial 128K words (12-bit) internal ROM, which is shared

by program and resource data. Program, voice and data are shared within this same

128K words ROM.

5.3 RAM

SNC26060P contains (64+16) nibble RAM <(64+16) x 4-bits>. The 64 nibble RAM is

only one page. Another 16 nibbles are 16 PWMIO duty registers. In our programming

structure, user can Directly use memory related command, M0 ~ M63 in the data

transfer type instructions, to access first 64 nibbles. Another 16 nibbles, user can use

PWMxL, PWMxH related command to access when PWMIO function is disabled.

(x can be 1~8)

5.4 Power Down Mode

“End” instruction makes the IC entering into Stop Mode will stop the system clock for

power savings (<3uA @VDD=3V and <6uA @VDD=4.5V.) Any valid data transition

(LꢁH or HꢁL) occurring on any IO pin can be used to start the system clock and

return to normal operating mode.

5.5 Sampling Rate Counter

The unique sampling rate counter is designed in voice channel to be able to play

diverse voices at different sample playing rates. The playing rate can be adaptively set

up among from the wide ranges of 2.5KHz to 20KHz. This architecture yields a

high-quality voice synthesis that sounds very close to its original source when played

through the same amplifier and speaker circuitry.
