CY7C53150, CY7C53120
Neuron Chip Network Processor
Features
■ Three 8-bit pipelined processors for concurrent processing of
application code and network traffic
■ On-chip LVD circuit to prevent nonvolatile memory corruption
during voltage drops
■ 11-pin I/O port programmable in 34 modes for fast application
program development
■ 2,048 bytes of SRAM for buffering network data, system, and
application data storage
■ Two 16-bit timer/counters for measuring and generating I/O
device waveforms
■ 512 bytes (CY7C53150), 2048 bytes (CY7C53120E2), 4096
bytes (CY7C53120E4) of Flash memory with on-chip charge
pump for flexible storage of configuration data and application
code
■ 5-pin communication port that supports direct connect and
network transceiver interfaces
■ Addresses up to 58 KB of external memory (CY7C53150)
■ Programmable pull-ups on I/O4–I/O7 and 20 mA sink current
on I/O0–I/O3
■ 10 KB (CY7C53120E2), 12 KB (CY7C53120E4) of ROM
containing LonTalk network protocol firmware
■ Unique 48-bit ID number in every device to facilitate network
installation and management
■ Maximum input clock operation of 20 MHz (CY7C53150),
10 MHz (CY7C53120E2), 40 MHz (CY7C53120E4) over a
–40°C to 85°C[2] temperature range
■ Low operating current; sleep mode operation for reduced
current consumption[1]
■ 64-pin TQFP package (CY7C53150)
■ 0.35 m flash process technology
■ 5.0 V operation
■ 32-pin SOIC or 44-pin TQFP package (CY7C53120)

Notes
1. Rare combinations of wake-up events occurring during the go to sleep sequence could produce unexpected sleep behavior.
2. Maximum Junction Temperature is 105 °C. T = T
+ V•I•JA. 32-pin SOIC JA = 51 °C/W. 44-pin TQFP JA = 43 °C/W. 64-pin TQFP JA = 44 °C/W.
