Quick Detail:
CHMOS 16-BIT MICROCONTROLLER
Description:
The 87C196LB is a high-performance 16-bit microcontroller with integrated support for the J1850 communication protocol. The 87C196LB is composed of a high-speed core with the following peripherals: an asynchronous/synchronous serial I/O port (8096 compatible) with a dedicated 16-bit baud-rate generator; an additional synchronous serial I/O port with full duplex master/slave transceivers; a six-channel A/D converter with sample and hold; a flexible timer/counter structure with prescaler, cascading, and quadrature capabilities; six modularized, multiplexed high-speed I/O for capture and compare (called event processor array) with 200 ns resolution and double buffered inputs; and a sophisticated prioritized interrupt structure with programmable peripheral transaction server (PTS). The clock doubler circuitry and oscillator output signal enable a 4 MHz
resonator to achieve the same internal clock speed as a more costly 8 MHz resonator in previous applications.
This same circuitry can drive other devices where a separate resonator was required in the past. Another costsavings feature is the fact that the I/O ports are driven low at reset, avoiding the need for pull-up resistors.
Applications:
â– 20 MHz operation†
â– 24 Kbytes of on-chip OTPROM
â– 768 bytes of on-chip register RAM
â– Register-to-register architecture
â– Peripheral transaction server (PTS)
with high-speed, microcoded interrupt service routines
â– Integrated, industry-standard J1850 communication protocol
â– Six-channel/10-bit A/D with sample and hold
â– High-speed event processor array
— Six capture/compare channels
— Two compare-only channels
â– Full-duplex serial I/O port with dedicated baud-rate generator
â– Enhanced full-duplex, synchronous serial I/O port (SSIO)
â– Programmable 8- or 16-bit external bus
â– Optional clock doubler with programmable clock output signal
â– SFR register that indicates the source of the last reset
â– Design enhancements for EMI reduction
â– Oscillator failure detection circuitry
â– Watchdog timer (WDT)
â– –40° C to +125° C ambient temperature
â– 52-pin PLCC package
