S3C2510A

PRODUCT OVERVIEW

1-9

Six Programmable Timer

The S3C2510A has six programmable timers. Each timer has its related pin, which is shared with programmable

I/O function. Each timer can be programmed two operation mode. One is interval mode and the other is toggle

mode. In interval mode, the initial timer output is set to low and it is set to high for 1 cycle time when timeout is

reached. therefore the timer output is shaped like pulse wave. In toggle mode, the timer output is toggled when

timeout is reached.

Hardware Watchdog Timer

The S3C2510A includes a watchdog timer, which is capable of generating system reset when the timeout value is

reached. The time value is ranged up to 2^30 system clock cycles. The watchdog timer is used to reset and restart

the system when a system has failed due to software error or to wrong response of external device.

Programmable Interrupt Controller

The S3C2510A has one programmable interrupt controller, which arranges the 36 programmable interrupt sources

by the programmable priority. The interrupt controller supports 36 maskable interrupt sources, where 30 interrupts

are from internal interrupts and 6 interrupts are from external interrupts. The interrupt with the highest priority is

reported to the CPU.

Programmable I/O Port Controller

The S3C2510A has 64 programmable I/O ports, which can be used for another function. If another function is

enabled, its I/O functionality is disabled. Six external interrupt request, four external DMA request, four external

DMA acknowledge, six timer outputs, 21 SAR signals, and 15 UART signals are multiplexed with I/O function.

Each I/O port can be programmed as Input or Output.

I

2C Controller

The S3C2510A has IIC controller, which enables the customer to implement a simple and cost effective inter-IC

connection. The IIC bus is a two-wire synchronous serial interface consisting of one data (SDA) and one clock

(SCL) line. The S3C2510A IIC controller operates in only single master mode.
