MC68307 TECHNICAL INFORMATION
MOTOROLA
The main features of the MC68307 include:
Static EC000 Core Processor—Identical to MC68EC000 Microprocessor
— Full compatibility with MC68000 and MC68EC000
— 24-bit address bus, for 16-Mbyte off-chip address space
— 16-bit on-chip data bus for MC68000 bus operations
— Static design allows processor clock to be stopped providing dramatic power savings
— 2.4 MIPS performance at 16.67-MHz processor clock
External M68000 Bus Interface with Dynamic Bus Sizing for 8-bit and 16-bit Data Ports
External 8-Bit Data Bus Interface (8051-Compatible)
M-Bus Module
— Provides interchip bus interface for EEPROMs, LCD controllers, A/D converters, etc.
— Compatible with industry-standard I2C bus
— Master or slave operation modes, supports multiple masters
— Automatic interrupt generation with programmable level
— Software-programmable clock frequency
— Data rates from 4–100 Kbit/s above 3.0-MHz system clock
Universal Asynchronous Receiver/Transmitter (UART) Module
— Flexible baud rate generator
— Based on MC68681 Dual Universal Asynchronous Receiver/Transmitter (DUART) programming
model
— 5 Mbits/s maximum transfer rate at 16.67-MHz system clock
— Automatic interrupt generation with programmable level
— Modem control signals available (CTS,RTS)
Timer Module
— Dual channel 16-bit general purpose counter/timer
— Multimode operation, independent capture/compare registers
— Automatic interrupt generation with programmable level
— Third 16-bit timer configured as a software watchdog
— 60-ns resolution at 16.67-MHz system clock
— Each timer has an input and an output pin
System Integration Module (SIM07), Incorporating Many Functions Typically Relegated to External Pro-
grammable Array Logic (PALs), Transistor-Transistor Logic (TTL), and ASICs, such as:
— System configuration, programmable address mapping
— System protection by hardware watchdog logic
— Power-down mode control, programmable processor clock driver
— Four programmable chip selects with wait state generation logic
— Three simple peripheral chip selects
— Parallel input/output ports, some with interrupt capability
— Programmed interrupt vector response for on-chip peripheral modules
— IEEE 1149.1 boundary scan test access port (JTAG)
Operation from DC to 16.67 MHz (Processor Clock)
Operating Voltages of 3.3V
± 0.3V and 5V ± 0.5V
Compact 100-Lead Quad Flat Pack (QFP) Package
