W529XX Application Note
- 24 -
adjusts the master frequency of the whole chip, while the latter method divides the master frequency by different
divisors to get the different 4.8/6/8/12 KHz sample rate clocks for the typical condition of F
OSC
= 1.5 MHz.
Normally, the user has to reproduce the voices at the same sample rate as recordings in order to get the
original voice outputs. The maximum sample rate allowed for the W529XX is 12 KHz, a limitation that is mainly
due to the access time of the ROM production chips.
During the development phase of application code, the user may use Winbond's speech download board or
OTP chip to evaluate the functions and voice quality. However it should be noted that the sample rate cannot be
set above 12 KHz, which is the maximum limitation of the W529XX, even though in practice it can work
normally. This is due to a fundamental difference of ROM structure between the evaluation tools and real chips.
15. W529XX PROGRAM FORMAT
The W529XX
PowerSpeech II
enables users to define the functions of their products using the W529XX
PowerSpeech
programming language. An example of the W529XX
PowerSpeech
program format is shown
below. (Explanatory notes follow the example.)
