SPC08A

6.5KB SOUND CONTROLLER

1. GENERAL DESCRIPTION

The SPC08A is a CPU based one-channel speech/melody synthesizer including CMOS 8-bit microprocessor with 69 instructions, 6.5K-byte ROM for speech and melody data (Speech is compressed by a 4-bit ADPCM with approx. 2 sec speech duration @ 7KHz sampling rate) and 64-byte working SRAM. It includes one Timer/Counter, 18 Software Selectable I/Os and one audio current output (D/A). For audio processing, melody and speech can be mixed into one output. It operates over a wide voltage range of 2.4V - 5.5V. In addition, the SPC08A has a Clock Stop mode for power saving. The power saving mode saves the RAM contents, but freezes the oscillator, causing all other chip functions to be inoperative. The Max. CPU clock frequency is 3.0MHz. It has an Instruction Cycle Rate of 2 clock cycles (min.) - 6 clock cycles (max.). The SPC08A includes, not only the latest technology, but also the full commitment and technical support of Sunplus.

Port A is a 6-bit bi-directional programmable Input / Output port with Pull-high or Open-drain option. As inputs, Port A can be in either the Pure or Pull-high states. As outputs, Port A can be either Buffer or Open-drain NMOS types (Sink current).

**See note 1 and 2 below.

Port B is a 6-bit bi-directional programmable Input / Output port with Pull-low or Open-drain option. As inputs, Port B can be in either the Pure or Pull-low states. As outputs, Port B can be either Buffer or Open-drain NMOS types (Sink current). IOC1: EXT INT IN IOC2: EXT COUNT IN

**See note 1 and 2 below.

Port D is a 6-bit bi-directional programmable Input/Output port with Pull-low or Open-drain option. As inputs, Port D can be either Pure or Pull-low states. As outputs, Port D can be either Buffer or Open-drain PMOS type (source current). (Key change, Wake up I/O)

**See note 1 and 2 below.

* Refer to SPC Programming Guide for complete information.

**Note: 1.) Three input states can be specified; Pure Input, Pull-High or Pull Low.

2.) Three output states can be specified, Buffer output, Open Drain PMOS output (source), or Open Drain NMOS

output (sink).

***OPT is the selection pin for ROSC or X’TAL using the bonding option. The shape looks like the figure at the right. When ROSC is selected, OPT is connected to VDD. If X’TAL is selected, OPT is floating. The reason OPT is near VDD is that when ROSC is selected, it is easy to make the connection between VDD and OPT.

6. FUNCTIONAL DESCRIPTIONS

6.1. CPU

The 8-bit microprocessor in SPC08A is a high performance processor equipped with Accumulator, Program Counter, X Register, Stack pointer and Processor Status Register (this is the same as the 6502 instruction structure).

6.6. Map of Memory and I/Os

Oscillator

The SPC08A supports AT-cut parallel resonant oscillated Crystal / Resonator or RC Oscillator or external clock sources by using the bonding option (select one from those three types). The design of application circuit should follow the vendors’ specifications or recommendations. The diagram below is typical of X’TAL/ROSC circuits for most applications:

Crystal Resonator/Rosc can be selected by bonding option.

6.4. ROM Area

The SPC08A provides a 6.5K-byte ROM that can be defined as the program area, audio data area, or both. To access ROM, users should program the BANK SELECT Register.

SPC08A contains one 12-bit timer/counter, TMA respectively. TMA can be specified as a timer or a counter. In the timer mode, the TMA is a re-loaded up-counter. When timer overflows, the user's pre-set value will be reloaded automatically and the timer

been activated, the value of the counter can also be read from the counters at the same time.

Clock source of Timer/Counter can be selected as follows:

6.9. Speech and Melody

Since SPC08A provides 6.5K ROM (0.5K for Sunplus test program) only, it is a suitable IC for simple speech and melody synthesis.

6.10. Power Saving Mode

The SPC08A provides a power saving mode (Standby mode) for those applications that require very low stand-by current. To enter standby mode, the Wake-Up Register should be enabled and then stop the CPU clock by writing the STOP CLOCK Register. The CPU will then go to the stand-by mode. In such a mode, RAM and I/Os will remain in their previous states until being awakened. Port IOD5 - 0 are the wake-up sources in SPC08A. After SPC08A is awakened, the internal CPU will go to the RESET State (Tw ≧ 65536 x T1) and then continue processing the program. Wakeup Reset will not affect the contents of RAM and I/Os (FIG.1).

For speech synthesis, SPC08A can provide NMI for accurate sampling frequency. Users can record or synthesize the sound and digitize it into the ROM. The sound data can be played back in the sequence of the control functions as designed by the user's program. Several algorithms are recommended for high fidelity and compression of sound including PCM, LOG PCM, and ADPCM.
