PCD3745AT规格书详情
GENERAL DESCRIPTION
The PCD3745A is a microcontroller oriented towards communication and metering applications. It has 4.5 kbytes of One Time Programmable (OTP) memory, 224 bytes RAM and 16 I/O lines.
The PCD3745A also incorporates a low power Real-Time Clock (RTC) and two low power 16-bit counters. The RTC runs using a 32 kHz crystal oscillator and is register adjustable. The RTC and the counters are able to operate in all microcontroller modes. The instruction set is based on that of the MAB8048 and is software compatible with the PCD33xxA family.
FEATURES
• 8-bit CPU, RAM and I/O
• 4.5 kbytes OTP memory; 224 bytes RAM
• 32 kHz adjustable crystal oscillator for real-time clock
• Over 100 instructions (based on MAB8048) all of 1 or 2 cycles
• 16 quasi-bidirectional I/O port lines
• 8-bit programmable Timer/event counter 1
• Two 16-bit counters with count inputs pins
• 2 single-level vectored interrupts:
– external; peripheral Counters 1 and 2; RTC alarm
– 8-bit programmable Timer/event counter 1
• Two test inputs, one of which also serves as the external interrupt input
• Stop and Idle modes for power saving
• Logic supply: 1.8 to 6 V
• CPU clock frequency: 1 to 16 MHz
• Operating temperature: −25 to +70 °C
• Manufactured in silicon gate CMOS process.
