Features
The eZ80F92 microcontroller is a member of
ZiLOG’s eZ80Acclaim! product f amily, which
offers Flash versions of ZiLOG’s eZ80® processor
core. An additional controller, the e Z80F93 , i s
intrinsically the same device, but offers smaller
memory sizes. The eZ80F92 and eZ80F93 devices
offer the following features:
• High-performance, pipelined eZ80F92 with single-cycle instruction fetch
– eZ80F92—128 KB on-chip Flash program
memory and an extra 256 bytes configuration
Flash memory; 8 KB on-chip high-speed
SRAM
– eZ80F93—64 KB on-chip Flash program
memory and an extra 256 bytes configuration
Flash memory, 4 KB on-chip high-speed
SRAM
• 24 General-Purpose I/O pins
• IrDA™-compatible Infrared Encoder/Decoder

• Real-time clock with on-chip 32 KHz oscillator,
selectable 50/60 Hz input, and separate VDD pin
for battery backup
• Glueless external memory interface with 4 Chip
Selects, independent WAIT state generators, and
external WAIT input pin; supports eZ80®, Z80,
Intel, and Motorola bus-compatible peripherals
• JTAG Debug Interface (also supports ZiLOG
Debug Interface)
• Interrupt controller supports internal and external maskable interrupts as well as a non maskable interrupt input
• New DMA-like eZ80® instructions
• Power management features including SLEEP/
HALT modes and peripheral power-down controls
• 100-pin LQFP package, pin-compatible with the
eZ80L92 microprocessor
• 3.0–3.6 V supply voltage with 5 V tolerant inputs
• Operating Temperature Ranges:
– Standard: 0ºC to +70ºC
– Extended: –40ºC to +105ºC
• 20 MHz versions:
– eZ80F92AZ020SC
– eZ80F92AZ020EC
– eZ80F93AZ020SC
