FUNCTION DESCRIPTIONS
5.1. Oscillator
SNC559 accept RC type oscillator for system clock. The typical circuit diagram for
oscillator is listed as follow.
r
OSC
VCC
RC Oscillator
5.2. ROM
SNC559 contains substantial 64K words (10-bit) internal ROM. Program, voices and
other data are shared with this same 64K words ROM.
5.3. RAM
SNC559 contains 128 nibbles RAM. The 128 nibbles RAM are divided into eight
pages (page 0 to page 7, 16 nibble RAM on each page). In our programming
structure, users can easily define and locate RAM page in the program. For instance,
users can use the instructions, PAGEn (n=0 to 7) to switch and indicate the RAM page.
Besides, users can use direct mode, M0 ~ M15 in the data transfer type instructions, to
access all 16 nibbles of each page.
5.4. Power Down Mode
“End” instruction will power down SNC559 and enable IC to consume fewer current for
power saving. (<3uA @VDD=3V and <5uA @VDD=5V) Please be aware that when
the power down mode is activated in SNC559, any valid data transition (L
H or H
L)
occurring on any input port (P1) or IO ports (P2, P3 and P6) will lead SNC559 back to
normal operation mode.
5.5. Sampling Rate Counters
Ver: 1.3

2 independent sampling rate counters are dedicated to 2 individual voice channels 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 feature
makes voice close to its original source and yield the better voice quality.
