eZ80L92 Processor Features
• Single-cycle instruction fetch, high-performance, pipelined eZ80^® CPU core
• Low power features including SLEEP mode, HALT mode, and selective
peripheral power-down control
• Two UARTs with independent baud rate generators
• SPI with independent clock rate generator
• I²C with independent clock rate generator
• Infrared Data Association (IrDA)-compliant infrared encoder/decoder
• New DMA-like eZ80^® instructions for efficient block data transfer
• Glueless external memory interface with 4 chip selects, individual wait state
generators, and an external WAIT input pin—supports Intel- and Motorola-style
buses
• Fixed-priority vectored interrupts (both internal and external) and interrupt
controller
• Real-time clock with on-chip 32KHz oscillator, selectable 50/60Hz input, and
separate V_DD pin for battery backup
• Six 16-bit Counter/Timers with prescalers and direct input/output drive
• Watch-Dog Timer
• 24 bits of general-purpose I/O
• JTAG and ZDI debug interfaces
• 100-pin LQFP package
• 3.0–3.6V supply voltage with 5V tolerant inputs
• Standard operating temperature range: 0ºC to +70ºC
Note: All signals with an overline are active Low. For example, B/W, for which
WORD is active Low, and B/W, for which BYTE is active Low.
