SNL310

16-Bit LCD Controller

1. INTRODUCTION

SNL310 is a high performance 16-bit DSP base processor with an 8-bit

microprocessor interface to drive various external devices, such as standard mask

ROM, Flash, SRAM and 1-bit/8-bit interface LCD drivers. Besides, this chip also

provides a UART interface to communicate with PC or other devices This chip is not

only a simply controller but also a powerful software voice synthesizer to realize voice

hi-compression, 4-ch wave-table melody.
