E2D0082-29-93 ¡ Semiconductor MSM9836-xxx ¡ Semiconductor Voice Synthesis IC with Built-in Mask ROM This version: Sep. 1999 MSM9836-xxx Previous version: May. 1997 GENERAL DESCRIPTION The MSM9836 is a PCM voice synthesis IC with built-in 3-Mbit mask ROM, D/A converter, and low-pass filter (LPF). The MSM9836 is specifically designed for applications that use a microcontroller. For this reason, functional support for standalone mode and RC oscillation has been omitted from the MSM9805, and the ROM capacity and the number of phrases have been increased. By using Oki's Sound Analysis and Editing Tool, ROM data such as Phrase Control Table can be easily set, created, edited, and evaluated. The following table lists the functional differences between the MSM9836 and the MSM9805. MSM9836 ROM Capacity Interface Oscillation Maximum Number of Phrases Status Signal 3 Mbits Microcontroller Ceramic 127 NAR/BUSY simultaneous output MSM9805 2 Mbits Microcontroller/Standalone Ceramic/RC 63 Only NAR output when operating in microcontroller interface mode FEATURES • 8-bit OKI nonlinear PCM method/8-bit Straight PCM method • Sampling frequency : 4.0 kHz/5.3 kHz/6.4 kHz/8.0 kHz/10.6 kHz/12.8 kHz/ (Can be set for each phrase) 16.0 kHz • ROM capacity : 3 Mbits • Maximum playback time : 97.7 sec (fSAM = 4.0 kHz) 73.7 sec (fSAM = 5.3 kHz) 61.0 sec (fSAM = 6.4 kHz) 48.8 sec (fSAM = 8.0 kHz) • Master clock frequency : 4.096 MHz (Ceramic oscillation/external clock input) • Edit ROM function • Maximum number of phrases : 127 • Built-in current mode 10-bit D/A converter • Built-in low-pass filter • Power supply voltage : +2.0 to +5.5 V • Package : 24-pin plastic SOP (SOP24-P-430-1.27-K) (Product name: MSM9836-xxxGS-K) xxx indicates code number.

At this time, oscillation 17 RESET I stops and AOUT output becomes GND level, then the IC returns to the initial state. Apply a "L" pulse upon power-on. This pin has an internal pull-up resistor. Signal output pin that indicates whether the 7-bit LATCH (see Block Diagram) is idle. 20 7 NAR EXTCK O I NAR at "H" level indicates that the LATCH is empty and ST input is enabled. Ceramic oscillator input/external clock input switching pin. Set to "H" level if ceramic oscillation.
