W536030P/060P/090P/120P
2. FEATURES
• Operating voltage: 2.4 volt ~ 5.5 volt
• Watch dog disabled/enabled by mask option
• Dual clock operating system
− Main clock with Ring/Crystal (400 KHz to 4 MHz)
− Sub-clock with 32.768 KHz RC/Crystal by mask option
• Memory
− Program ROM (P-ROM): 8 K × 20 (ROM Bank0)
− Data RAM (W-RAM): 1K × 4 bit
(RAM Bank 0 is 512 nibbles from 0: 000~0: 1FF and 0:380~0:3FF are mapped to special
register.
RAM Bank F is 512 nibbles from F: 200~F: 3FF either data RAM or dedicated to script
kernel)
• Maximum 32 input/output pads
− Ports for input only: 12 pads (RC, RD and RG port; RG for W536090P/120P only)
