Quick Detail:
80C51 8-bit microcontroller family 2K/64 OTP/ROM, 5 channel 8-bit A/D, PWM, low pin count
Description:
The 83C749/87C749 offers many of the advantages of the 80C51 architecture in a small package and at low cost.
The 8XC749 Microcontroller is fabricated with high-density CMOS technology. epitaxial substrate minimizes CMOS latch-up sensitivity.
The 8XC749 contains a 2k × 8 ROM (83C749) EPROM (87C749), a
64 × 8 RAM, 21 I/O lines, a 16-bit auto-reload counter/timer, a fixed-priority level interrupt structure, an on-chip oscillator, a five channel multiplexed 8-bit A/D converter, and an 8-bit PWM output.
The EPROM version of this device, the 87C749, is available in plastic one-time programmable (OTP) packages. Once the array has been programmed, it is functionally equivalent to the masked ROM 83C749. Thus, unless explicitly stated otherwise, all references made to the 83C749 apply equally to the 87C749.
The 83C749 supports two power reduction modes of operation referred to as the idle mode and the power-down mode.
Applications:
• Available in erasable quartz lid or One-Time Programmable plastic packages
• 80C51 based architecture
• Small package sizes
– 28-pin DIP
– 28-pin Shrink Small Outline Package (SSOP)
– 28-pin PLCC
• Wide oscillator frequency range: 3.5MHz to 16MHz
• Low power consumption:
– Normal operation: less than 11mA @ 5V, 12MHz
– Idle mode
– Power-down mode
• 2k × 8 ROM (83C749) EPROM (87C749)
• 64 × 8 RAM
• 16-bit auto reloadable counter/timer
• 5-channel 8-bit A/D converter
• 8-bit PWM output/timer
• 10-bit fixed-rate timer
• Boolean processor
• CMOS and TTL compatible
• Well suited for logic replacement, consumer and industrial applications
