LC863516B omOverview
.cThe LC863548/40/32/28/24/20/16B are 8-bit single chip microcontrollers with the following on-chip functional blocks :
• CPU : Operable at a minimum bus cycle time of 0.424µs
U• On-chip ROM capacity
Program ROM : 48K/40K/32K/28K/24K/20K/16K-bytes
t4CGROM
: 16K-bytes
• On-chip RAM capacity : 640/512-bytes
e• OSD RAM : 176 × 9-bits
• On-screen display controller
e• Four channels × 6-bit AD Converter
h• Three channels × 7-bit PWM
• Two channels × 16-bit timer/counter, 14-bit base timer
S• IIC-bus compliant serial interface circuit (Multi-master type)
• ROM correction function
ta• 13-source 8-vectored interrupt system
• Integrated system clock generator and display clock generator
aOnly one X’tal oscillator (32.768kHz) for PLL reference is used for both generators.
www.DAll of the above functions are fabricated on a single chip.
