Description The CXP913040 is a CMOS 16-bit microcomputer integrating on a single chip an A/D converter, serial interface with an incorporated buffer RAM, highprecision timing pattern generation function, pulse cycle measurement circuit, PWM generator, generalpurpose prescaler, vertical sync separation circuit, and a measurement circuit which measures the signals of capstan FG, drum FG/PG, reel FG and other servo systems with high precision, as well as basic configurations like a 16-bit CPU, ROM, RAM, and I/O port. This LSI also provides sleep/stop modes that enable lower power consumption. Features • An efficient instruction set as a controller — Direct addressing, numerous abbreviated forms, multiplication and division instructions • Instruction sets for C language and RTOS — Highly quadratic instruction system, general-purpose register of 16-bit × 8-pin × 16-bank configuration • Minimum instruction cycle time 100ns at 20MHz operation • Incorporated ROM capacity 160K bytes • Incorporated RAM capacity 6144 bytes • Peripheral functions — A/D converter 8-bit 12-channel successive approximation system, automatic scanning function, 8-stage (soft) + 4-stage (hard) FIFO for conversion results (Conversion time: 20µs at 20MHz) — Serial interface Buffer RAM (128 bytes, supports high-speed transfer mode), 3 channels — Timers 8-bit timer/counter + 8-bit timer (with timing output), 1 channel 16-bit capture timer/counter (with timing output), 1 channel 16-bit timer, 4 channels — High-precision timing pattern generator PPG for 27 pins, 42 stages (max.) PPG for 16 pins, 16 stages (max.) RTG for 5 pins, 3 channels — PWM/DA gate output PWM for 14 bits, 2 channels (Repetitive frequency of 39.1kHz, 20MHz) DA gate pulse for 14 bits, 2 channels — Servo input control Capstan FG, drum FG/PG, reel FG — VSYNC separator — FRC capture unit 24-bit and 8-stage FIFO — PWM output 14 bits, 2 channels — General-purpose prescaler 10 bits, 1 channel — Pulse cycle measurement circuit 1 channel with mask input • General-purpose I/O 80 pins (max.; when all multi-purpose pins are used as general-purpose I/O.) • Interruption 28 factors, 28 vectors, multi-interruption and priority selection possible • Standby mode Sleep/stop • Package 100-pin plastic LQFP • Piggy/evaluation chip CXP913000 100-pin ceramic LQFP
